Helpers
Introduction
LaraGram includes a variety of global "helper" PHP functions. Many of these functions are used by the framework itself; however, you are free to use them in your own applications if you find them convenient.

Arrays & Objects
Arr::accessible()
The Arr::accessible method determines if the given value is array accessible:
use LaraGram\Support\Arr;
use LaraGram\Support\Collection;
$isAccessible = Arr::accessible(['a' => 1, 'b' => 2]);
// true
$isAccessible = Arr::accessible(new Collection);
// true
$isAccessible = Arr::accessible('abc');
// false
$isAccessible = Arr::accessible(new stdClass);
// falseArr::add()
The Arr::add method adds a given key / value pair to an array if the given key doesn't already exist in the array or is set to null:
use LaraGram\Support\Arr;
$array = Arr::add(['name' => 'Desk'], 'price', 100);
// ['name' => 'Desk', 'price' => 100]
$array = Arr::add(['name' => 'Desk', 'price' => null], 'price', 100);
// ['name' => 'Desk', 'price' => 100]Arr::array()
The Arr::array method retrieves a value from a deeply nested array using "dot" notation (just as Arr::get() does), but throws an InvalidArgumentException if the requested value is not an array:
use LaraGram\Support\Arr;
$array = ['name' => 'Joe', 'languages' => ['PHP', 'Ruby']];
$value = Arr::array($array, 'languages');
// ['PHP', 'Ruby']
$value = Arr::array($array, 'name');
// throws InvalidArgumentExceptionArr::boolean()
The Arr::boolean method retrieves a value from a deeply nested array using "dot" notation (just as Arr::get() does), but throws an InvalidArgumentException if the requested value is not a boolean:
use LaraGram\Support\Arr;
$array = ['name' => 'Joe', 'available' => true];
$value = Arr::boolean($array, 'available');
// true
$value = Arr::boolean($array, 'name');
// throws InvalidArgumentExceptionArr::collapse()
The Arr::collapse method collapses an array of arrays or collections into a single array:
use LaraGram\Support\Arr;
$array = Arr::collapse([[1, 2, 3], [4, 5, 6], [7, 8, 9]]);
// [1, 2, 3, 4, 5, 6, 7, 8, 9]Arr::crossJoin()
The Arr::crossJoin method cross joins the given arrays, returning a Cartesian product with all possible permutations:
use LaraGram\Support\Arr;
$matrix = Arr::crossJoin([1, 2], ['a', 'b']);
/*
[
[1, 'a'],
[1, 'b'],
[2, 'a'],
[2, 'b'],
]
*/
$matrix = Arr::crossJoin([1, 2], ['a', 'b'], ['I', 'II']);
/*
[
[1, 'a', 'I'],
[1, 'a', 'II'],
[1, 'b', 'I'],
[1, 'b', 'II'],
[2, 'a', 'I'],
[2, 'a', 'II'],
[2, 'b', 'I'],
[2, 'b', 'II'],
]
*/Arr::divide()
The Arr::divide method returns two arrays: one containing the keys and the other containing the values of the given array:
use LaraGram\Support\Arr;
[$keys, $values] = Arr::divide(['name' => 'Desk']);
// $keys: ['name']
// $values: ['Desk']Arr::dot()
The Arr::dot method flattens a multi-dimensional array into a single level array that uses "dot" notation to indicate depth:
use LaraGram\Support\Arr;
$array = ['products' => ['desk' => ['price' => 100]]];
$flattened = Arr::dot($array);
// ['products.desk.price' => 100]Arr::except()
The Arr::except method removes the given key / value pairs from an array:
use LaraGram\Support\Arr;
$array = ['name' => 'Desk', 'price' => 100];
$filtered = Arr::except($array, ['price']);
// ['name' => 'Desk']Arr::exists()
The Arr::exists method checks that the given key exists in the provided array:
use LaraGram\Support\Arr;
$array = ['name' => 'John Doe', 'age' => 17];
$exists = Arr::exists($array, 'name');
// true
$exists = Arr::exists($array, 'salary');
// falseArr::first()
The Arr::first method returns the first element of an array passing a given truth test:
use LaraGram\Support\Arr;
$array = [100, 200, 300];
$first = Arr::first($array, function (int $value, int $key) {
return $value >= 150;
});
// 200A default value may also be passed as the third parameter to the method. This value will be returned if no value passes the truth test:
use LaraGram\Support\Arr;
$first = Arr::first($array, $callback, $default);Arr::flatten()
The Arr::flatten method flattens a multi-dimensional array into a single level array:
use LaraGram\Support\Arr;
$array = ['name' => 'Joe', 'languages' => ['PHP', 'Ruby']];
$flattened = Arr::flatten($array);
// ['Joe', 'PHP', 'Ruby']Arr::float()
The Arr::float method retrieves a value from a deeply nested array using "dot" notation (just as Arr::get() does), but throws an InvalidArgumentException if the requested value is not a float:
use LaraGram\Support\Arr;
$array = ['name' => 'Joe', 'balance' => 123.45];
$value = Arr::float($array, 'balance');
// 123.45
$value = Arr::float($array, 'name');
// throws InvalidArgumentExceptionArr::forget()
The Arr::forget method removes a given key / value pairs from a deeply nested array using "dot" notation:
use LaraGram\Support\Arr;
$array = ['products' => ['desk' => ['price' => 100]]];
Arr::forget($array, 'products.desk');
// ['products' => []]Arr::from()
The Arr::from method converts various input types into a plain PHP array. It supports a range of input types, including arrays, objects, and several common LaraGram interfaces, such as Arrayable, Enumerable, Jsonable, and JsonSerializable. Additionally, it handles Traversable and WeakMap instances:
use LaraGram\Support\Arr;
Arr::from((object) ['foo' => 'bar']); // ['foo' => 'bar']
class TestJsonableObject implements Jsonable
{
public function toJson($options = 0)
{
return json_encode(['foo' => 'bar']);
}
}
Arr::from(new TestJsonableObject); // ['foo' => 'bar']Arr::get()
The Arr::get method retrieves a value from a deeply nested array using "dot" notation:
use LaraGram\Support\Arr;
$array = ['products' => ['desk' => ['price' => 100]]];
$price = Arr::get($array, 'products.desk.price');
// 100The Arr::get method also accepts a default value, which will be returned if the specified key is not present in the array:
use LaraGram\Support\Arr;
$discount = Arr::get($array, 'products.desk.discount', 0);
// 0Arr::has()
The Arr::has method checks whether a given item or items exists in an array using "dot" notation:
use LaraGram\Support\Arr;
$array = ['product' => ['name' => 'Desk', 'price' => 100]];
$contains = Arr::has($array, 'product.name');
// true
$contains = Arr::has($array, ['product.price', 'product.discount']);
// falseArr::hasAll()
The Arr::hasAll method determines if all of the specified keys exist in the given array using "dot" notation:
use LaraGram\Support\Arr;
$array = ['name' => 'Taylor', 'language' => 'PHP'];
Arr::hasAll($array, ['name']); // true
Arr::hasAll($array, ['name', 'language']); // true
Arr::hasAll($array, ['name', 'IDE']); // falseArr::hasAny()
The Arr::hasAny method checks whether any item in a given set exists in an array using "dot" notation:
use LaraGram\Support\Arr;
$array = ['product' => ['name' => 'Desk', 'price' => 100]];
$contains = Arr::hasAny($array, 'product.name');
// true
$contains = Arr::hasAny($array, ['product.name', 'product.discount']);
// true
$contains = Arr::hasAny($array, ['category', 'product.discount']);
// falseArr::integer()
The Arr::integer method retrieves a value from a deeply nested array using "dot" notation (just as Arr::get() does), but throws an InvalidArgumentException if the requested value is not an int:
use LaraGram\Support\Arr;
$array = ['name' => 'Joe', 'age' => 42];
$value = Arr::integer($array, 'age');
// 42
$value = Arr::integer($array, 'name');
// throws InvalidArgumentExceptionArr::isAssoc()
The Arr::isAssoc method returns true if the given array is an associative array. An array is considered "associative" if it doesn't have sequential numerical keys beginning with zero:
use LaraGram\Support\Arr;
$isAssoc = Arr::isAssoc(['product' => ['name' => 'Desk', 'price' => 100]]);
// true
$isAssoc = Arr::isAssoc([1, 2, 3]);
// falseArr::isList()
The Arr::isList method returns true if the given array's keys are sequential integers beginning from zero:
use LaraGram\Support\Arr;
$isList = Arr::isList(['foo', 'bar', 'baz']);
// true
$isList = Arr::isList(['product' => ['name' => 'Desk', 'price' => 100]]);
// falseArr::join()
The Arr::join method joins array elements with a string. Using this method's third argument, you may also specify the joining string for the final element of the array:
use LaraGram\Support\Arr;
$array = ['Tailwind', 'Alpine', 'LaraGram', 'Livewire'];
$joined = Arr::join($array, ', ');
// Tailwind, Alpine, LaraGram, Livewire
$joined = Arr::join($array, ', ', ', and ');
// Tailwind, Alpine, LaraGram, and LivewireArr::keyBy()
The Arr::keyBy method keys the array by the given key. If multiple items have the same key, only the last one will appear in the new array:
use LaraGram\Support\Arr;
$array = [
['product_id' => 'prod-100', 'name' => 'Desk'],
['product_id' => 'prod-200', 'name' => 'Chair'],
];
$keyed = Arr::keyBy($array, 'product_id');
/*
[
'prod-100' => ['product_id' => 'prod-100', 'name' => 'Desk'],
'prod-200' => ['product_id' => 'prod-200', 'name' => 'Chair'],
]
*/Arr::last()
The Arr::last method returns the last element of an array passing a given truth test:
use LaraGram\Support\Arr;
$array = [100, 200, 300, 110];
$last = Arr::last($array, function (int $value, int $key) {
return $value >= 150;
});
// 300A default value may be passed as the third argument to the method. This value will be returned if no value passes the truth test:
use LaraGram\Support\Arr;
$last = Arr::last($array, $callback, $default);Arr::map()
The Arr::map method iterates through the array and passes each value and key to the given callback. The array value is replaced by the value returned by the callback:
use LaraGram\Support\Arr;
$array = ['first' => 'james', 'last' => 'kirk'];
$mapped = Arr::map($array, function (string $value, string $key) {
return ucfirst($value);
});
// ['first' => 'James', 'last' => 'Kirk']Arr::mapSpread()
The Arr::mapSpread method iterates over the array, passing each nested item value into the given closure. The closure is free to modify the item and return it, thus forming a new array of modified items:
use LaraGram\Support\Arr;
$array = [
[0, 1],
[2, 3],
[4, 5],
[6, 7],
[8, 9],
];
$mapped = Arr::mapSpread($array, function (int $even, int $odd) {
return $even + $odd;
});
/*
[1, 5, 9, 13, 17]
*/Arr::mapWithKeys()
The Arr::mapWithKeys method iterates through the array and passes each value to the given callback. The callback should return an associative array containing a single key / value pair:
use LaraGram\Support\Arr;
$array = [
[
'name' => 'John',
'department' => 'Sales',
'email' => 'john@example.com',
],
[
'name' => 'Jane',
'department' => 'Marketing',
'email' => 'jane@example.com',
]
];
$mapped = Arr::mapWithKeys($array, function (array $item, int $key) {
return [$item['email'] => $item['name']];
});
/*
[
'john@example.com' => 'John',
'jane@example.com' => 'Jane',
]
*/Arr::only()
The Arr::only method returns only the specified key / value pairs from the given array:
use LaraGram\Support\Arr;
$array = ['name' => 'Desk', 'price' => 100, 'orders' => 10];
$slice = Arr::only($array, ['name', 'price']);
// ['name' => 'Desk', 'price' => 100]Arr::partition()
The Arr::partition method may be combined with PHP array destructuring to separate elements that pass a given truth test from those that do not:
<?php
use LaraGram\Support\Arr;
$numbers = [1, 2, 3, 4, 5, 6];
[$underThree, $equalOrAboveThree] = Arr::partition($numbers, function (int $i) {
return $i < 3;
});
dump($underThree);
// [1, 2]
dump($equalOrAboveThree);
// [3, 4, 5, 6]Arr::pluck()
The Arr::pluck method retrieves all of the values for a given key from an array:
use LaraGram\Support\Arr;
$array = [
['developer' => ['id' => 1, 'name' => 'Taylor']],
['developer' => ['id' => 2, 'name' => 'Abigail']],
];
$names = Arr::pluck($array, 'developer.name');
// ['Taylor', 'Abigail']You may also specify how you wish the resulting list to be keyed:
use LaraGram\Support\Arr;
$names = Arr::pluck($array, 'developer.name', 'developer.id');
// [1 => 'Taylor', 2 => 'Abigail']Arr::prepend()
The Arr::prepend method will push an item onto the beginning of an array:
use LaraGram\Support\Arr;
$array = ['one', 'two', 'three', 'four'];
$array = Arr::prepend($array, 'zero');
// ['zero', 'one', 'two', 'three', 'four']If needed, you may specify the key that should be used for the value:
use LaraGram\Support\Arr;
$array = ['price' => 100];
$array = Arr::prepend($array, 'Desk', 'name');
// ['name' => 'Desk', 'price' => 100]Arr::prependKeysWith()
The Arr::prependKeysWith prepends all key names of an associative array with the given prefix:
use LaraGram\Support\Arr;
$array = [
'name' => 'Desk',
'price' => 100,
];
$keyed = Arr::prependKeysWith($array, 'product.');
/*
[
'product.name' => 'Desk',
'product.price' => 100,
]
*/Arr::pull()
The Arr::pull method returns and removes a key / value pair from an array:
use LaraGram\Support\Arr;
$array = ['name' => 'Desk', 'price' => 100];
$name = Arr::pull($array, 'name');
// $name: Desk
// $array: ['price' => 100]A default value may be passed as the third argument to the method. This value will be returned if the key doesn't exist:
use LaraGram\Support\Arr;
$value = Arr::pull($array, $key, $default);Arr::query()
The Arr::query method converts the array into a query string:
use LaraGram\Support\Arr;
$array = [
'name' => 'Taylor',
'order' => [
'column' => 'created_at',
'direction' => 'desc'
]
];
Arr::query($array);
// name=Taylor&order[column]=created_at&order[direction]=descArr::random()
The Arr::random method returns a random value from an array:
use LaraGram\Support\Arr;
$array = [1, 2, 3, 4, 5];
$random = Arr::random($array);
// 4 - (retrieved randomly)You may also specify the number of items to return as an optional second argument. Note that providing this argument will return an array even if only one item is desired:
use LaraGram\Support\Arr;
$items = Arr::random($array, 2);
// [2, 5] - (retrieved randomly)Arr::reject()
The Arr::reject method removes items from an array using the given closure:
use LaraGram\Support\Arr;
$array = [100, '200', 300, '400', 500];
$filtered = Arr::reject($array, function (string|int $value, int $key) {
return is_string($value);
});
// [0 => 100, 2 => 300, 4 => 500]Arr::select()
The Arr::select method selects an array of values from an array:
use LaraGram\Support\Arr;
$array = [
['id' => 1, 'name' => 'Desk', 'price' => 200],
['id' => 2, 'name' => 'Table', 'price' => 150],
['id' => 3, 'name' => 'Chair', 'price' => 300],
];
Arr::select($array, ['name', 'price']);
// [['name' => 'Desk', 'price' => 200], ['name' => 'Table', 'price' => 150], ['name' => 'Chair', 'price' => 300]]Arr::set()
The Arr::set method sets a value within a deeply nested array using "dot" notation:
use LaraGram\Support\Arr;
$array = ['products' => ['desk' => ['price' => 100]]];
Arr::set($array, 'products.desk.price', 200);
// ['products' => ['desk' => ['price' => 200]]]Arr::shuffle()
The Arr::shuffle method randomly shuffles the items in the array:
use LaraGram\Support\Arr;
$array = Arr::shuffle([1, 2, 3, 4, 5]);
// [3, 2, 5, 1, 4] - (generated randomly)Arr::sole()
The Arr::sole method retrieves a single value from an array using the given closure. If more than one value within the array matches the given truth test, an LaraGram\Support\MultipleItemsFoundException exception will be thrown. If no values match the truth test, an LaraGram\Support\ItemNotFoundException exception will be thrown:
use LaraGram\Support\Arr;
$array = ['Desk', 'Table', 'Chair'];
$value = Arr::sole($array, fn (string $value) => $value === 'Desk');
// 'Desk'Arr::sort()
The Arr::sort method sorts an array by its values:
use LaraGram\Support\Arr;
$array = ['Desk', 'Table', 'Chair'];
$sorted = Arr::sort($array);
// ['Chair', 'Desk', 'Table']You may also sort the array by the results of a given closure:
use LaraGram\Support\Arr;
$array = [
['name' => 'Desk'],
['name' => 'Table'],
['name' => 'Chair'],
];
$sorted = array_values(Arr::sort($array, function (array $value) {
return $value['name'];
}));
/*
[
['name' => 'Chair'],
['name' => 'Desk'],
['name' => 'Table'],
]
*/Arr::sortDesc()
The Arr::sortDesc method sorts an array in descending order by its values:
use LaraGram\Support\Arr;
$array = ['Desk', 'Table', 'Chair'];
$sorted = Arr::sortDesc($array);
// ['Table', 'Desk', 'Chair']You may also sort the array by the results of a given closure:
use LaraGram\Support\Arr;
$array = [
['name' => 'Desk'],
['name' => 'Table'],
['name' => 'Chair'],
];
$sorted = array_values(Arr::sortDesc($array, function (array $value) {
return $value['name'];
}));
/*
[
['name' => 'Table'],
['name' => 'Desk'],
['name' => 'Chair'],
]
*/Arr::sortRecursive()
The Arr::sortRecursive method recursively sorts an array using the sort function for numerically indexed sub-arrays and the ksort function for associative sub-arrays:
use LaraGram\Support\Arr;
$array = [
['Roman', 'Taylor', 'Li'],
['PHP', 'Ruby', 'JavaScript'],
['one' => 1, 'two' => 2, 'three' => 3],
];
$sorted = Arr::sortRecursive($array);
/*
[
['JavaScript', 'PHP', 'Ruby'],
['one' => 1, 'three' => 3, 'two' => 2],
['Li', 'Roman', 'Taylor'],
]
*/If you would like the results sorted in descending order, you may use the Arr::sortRecursiveDesc method.
$sorted = Arr::sortRecursiveDesc($array);Arr::string()
The Arr::string method retrieves a value from a deeply nested array using "dot" notation (just as Arr::get() does), but throws an InvalidArgumentException if the requested value is not a string:
use LaraGram\Support\Arr;
$array = ['name' => 'Joe', 'languages' => ['PHP', 'Ruby']];
$value = Arr::string($array, 'name');
// Joe
$value = Arr::string($array, 'languages');
// throws InvalidArgumentExceptionArr::take()
The Arr::take method returns a new array with the specified number of items:
use LaraGram\Support\Arr;
$array = [0, 1, 2, 3, 4, 5];
$chunk = Arr::take($array, 3);
// [0, 1, 2]You may also pass a negative integer to take the specified number of items from the end of the array:
$array = [0, 1, 2, 3, 4, 5];
$chunk = Arr::take($array, -2);
// [4, 5]Arr::toCssClasses()
The Arr::toCssClasses method conditionally compiles a CSS class string. The method accepts an array of classes where the array key contains the class or classes you wish to add, while the value is a boolean expression. If the array element has a numeric key, it will always be included in the rendered class list:
use LaraGram\Support\Arr;
$isActive = false;
$hasError = true;
$array = ['p-4', 'font-bold' => $isActive, 'bg-red' => $hasError];
$classes = Arr::toCssClasses($array);
/*
'p-4 bg-red'
*/Arr::toCssStyles()
The Arr::toCssStyles conditionally compiles a CSS style string. The method accepts an array of classes where the array key contains the class or classes you wish to add, while the value is a boolean expression. If the array element has a numeric key, it will always be included in the rendered class list:
use LaraGram\Support\Arr;
$hasColor = true;
$array = ['background-color: blue', 'color: blue' => $hasColor];
$classes = Arr::toCssStyles($array);
/*
'background-color: blue; color: blue;'
*/This method powers LaraGram's functionality allowing merging classes with a Blade component's attribute bag as well as the @class Blade directive.
Arr::undot()
The Arr::undot method expands a single-dimensional array that uses "dot" notation into a multi-dimensional array:
use LaraGram\Support\Arr;
$array = [
'user.name' => 'Kevin Malone',
'user.occupation' => 'Accountant',
];
$array = Arr::undot($array);
// ['user' => ['name' => 'Kevin Malone', 'occupation' => 'Accountant']]Arr::where()
The Arr::where method filters an array using the given closure:
use LaraGram\Support\Arr;
$array = [100, '200', 300, '400', 500];
$filtered = Arr::where($array, function (string|int $value, int $key) {
return is_string($value);
});
// [1 => '200', 3 => '400']Arr::whereNotNull()
The Arr::whereNotNull method removes all null values from the given array:
use LaraGram\Support\Arr;
$array = [0, null];
$filtered = Arr::whereNotNull($array);
// [0 => 0]Arr::wrap()
The Arr::wrap method wraps the given value in an array. If the given value is already an array it will be returned without modification:
use LaraGram\Support\Arr;
$string = 'LaraGram';
$array = Arr::wrap($string);
// ['LaraGram']If the given value is null, an empty array will be returned:
use LaraGram\Support\Arr;
$array = Arr::wrap(null);
// []data_fill()
The data_fill function sets a missing value within a nested array or object using "dot" notation:
$data = ['products' => ['desk' => ['price' => 100]]];
data_fill($data, 'products.desk.price', 200);
// ['products' => ['desk' => ['price' => 100]]]
data_fill($data, 'products.desk.discount', 10);
// ['products' => ['desk' => ['price' => 100, 'discount' => 10]]]This function also accepts asterisks as wildcards and will fill the target accordingly:
$data = [
'products' => [
['name' => 'Desk 1', 'price' => 100],
['name' => 'Desk 2'],
],
];
data_fill($data, 'products.*.price', 200);
/*
[
'products' => [
['name' => 'Desk 1', 'price' => 100],
['name' => 'Desk 2', 'price' => 200],
],
]
*/data_get()
The data_get function retrieves a value from a nested array or object using "dot" notation:
$data = ['products' => ['desk' => ['price' => 100]]];
$price = data_get($data, 'products.desk.price');
// 100The data_get function also accepts a default value, which will be returned if the specified key is not found:
$discount = data_get($data, 'products.desk.discount', 0);
// 0The function also accepts wildcards using asterisks, which may target any key of the array or object:
$data = [
'product-one' => ['name' => 'Desk 1', 'price' => 100],
'product-two' => ['name' => 'Desk 2', 'price' => 150],
];
data_get($data, '*.name');
// ['Desk 1', 'Desk 2'];The {first} and {last} placeholders may be used to retrieve the first or last items in an array:
$flight = [
'segments' => [
['from' => 'LHR', 'departure' => '9:00', 'to' => 'IST', 'arrival' => '15:00'],
['from' => 'IST', 'departure' => '16:00', 'to' => 'PKX', 'arrival' => '20:00'],
],
];
data_get($flight, 'segments.{first}.arrival');
// 15:00data_set()
The data_set function sets a value within a nested array or object using "dot" notation:
$data = ['products' => ['desk' => ['price' => 100]]];
data_set($data, 'products.desk.price', 200);
// ['products' => ['desk' => ['price' => 200]]]This function also accepts wildcards using asterisks and will set values on the target accordingly:
$data = [
'products' => [
['name' => 'Desk 1', 'price' => 100],
['name' => 'Desk 2', 'price' => 150],
],
];
data_set($data, 'products.*.price', 200);
/*
[
'products' => [
['name' => 'Desk 1', 'price' => 200],
['name' => 'Desk 2', 'price' => 200],
],
]
*/By default, any existing values are overwritten. If you wish to only set a value if it doesn't exist, you may pass false as the fourth argument to the function:
$data = ['products' => ['desk' => ['price' => 100]]];
data_set($data, 'products.desk.price', 200, overwrite: false);
// ['products' => ['desk' => ['price' => 100]]]data_forget()
The data_forget function removes a value within a nested array or object using "dot" notation:
$data = ['products' => ['desk' => ['price' => 100]]];
data_forget($data, 'products.desk.price');
// ['products' => ['desk' => []]]This function also accepts wildcards using asterisks and will remove values on the target accordingly:
$data = [
'products' => [
['name' => 'Desk 1', 'price' => 100],
['name' => 'Desk 2', 'price' => 150],
],
];
data_forget($data, 'products.*.price');
/*
[
'products' => [
['name' => 'Desk 1'],
['name' => 'Desk 2'],
],
]
*/head()
The head function returns the first element in the given array. If the array is empty, false will be returned:
$array = [100, 200, 300];
$first = head($array);
// 100last()
The last function returns the last element in the given array. If the array is empty, false will be returned:
$array = [100, 200, 300];
$last = last($array);
// 300Numbers
Number::abbreviate()
The Number::abbreviate method returns the human-readable format of the provided numerical value, with an abbreviation for the units:

// 2nd
$number = Number::ordinal(21);
// 21stNumber::pairs()
The Number::pairs method generates an array of number pairs (sub-ranges) based on a specified range and step value. This method can be useful for dividing a larger range of numbers into smaller, manageable sub-ranges for things like pagination or batching tasks. The pairs method returns an array of arrays, where each inner array represents a pair (sub-range) of numbers:
use LaraGram\Support\Number;
$result = Number::pairs(25, 10);
// [[0, 9], [10, 19], [20, 25]]
$result = Number::pairs(25, 10, offset: 0);

// (int) 10
$result = Number::parseInt('10,123', locale: 'fr');
// (int) 10Number::parseFloat()
The Number::parseFloat method parse a string into a float according to the specified locale:
use LaraGram\Support\Number;
$result = Number::parseFloat('10');
// (float) 10.0
$result = Number::parseFloat('10', locale: 'fr');
// (float) 10.0Number::percentage()
The Number::percentage method returns the percentage representation of the given value as a string:
use LaraGram\Support\Number;
$percentage = Number::percentage(10);
// 10%
$percentage = Number::percentage(10, precision: 2);
// 10.00%
$percentage = Number::percentage(10.123, maxPrecision: 2);
// 10.12%
$percentage = Number::percentage(10, precision: 2, locale: 'de');
// 10,00%Number::spell()
The Number::spell method transforms the given number into a string of words:
use LaraGram\Support\Number;
$number = Number::spell(102);
// one hundred and two
$number = Number::spell(88, locale: 'fr');
// quatre-vingt-huitThe after argument allows you to specify a value after which all numbers should be spelled out:
$number = Number::spell(10, after: 10);
// 10
$number = Number::spell(11, after: 10);
// elevenThe until argument allows you to specify a value before which all numbers should be spelled out:
$number = Number::spell(5, until: 10);
// five
$number = Number::spell(10, until: 10);
// 10Number::spellOrdinal()
The Number::spellOrdinal method returns the number's ordinal representation as a string of words:
use LaraGram\Support\Number;
$number = Number::spellOrdinal(1);
// first
$number = Number::spellOrdinal(2);
// second
$number = Number::spellOrdinal(21);
// twenty-firstNumber::trim()
The Number::trim method removes any trailing zero digits after the decimal point of the given number:
use LaraGram\Support\Number;
$number = Number::trim(12.0);
// 12
$number = Number::trim(12.30);
// 12.3Number::useLocale()
The Number::useLocale method sets the default number locale globally, which affects how numbers and currency are formatted by subsequent invocations to the Number class's methods:
use LaraGram\Support\Number;
/**
* Bootstrap any application services.
*/
public function boot(): void
{
Number::useLocale('de');
}Number::withLocale()
The Number::withLocale method executes the given closure using the specified locale and then restores the original locale after the callback has executed:
use LaraGram\Support\Number;
$number = Number::withLocale('de', function () {
return Number::format(1500);
});Number::useCurrency()
The Number::useCurrency method sets the default number currency globally, which affects how the currency is formatted by subsequent invocations to the Number class's methods:
use LaraGram\Support\Number;
/**
* Bootstrap any application services.
*/
public function boot(): void
{
Number::useCurrency('GBP');
}Number::withCurrency()
The Number::withCurrency method executes the given closure using the specified currency and then restores the original currency after the callback has executed:
use LaraGram\Support\Number;
$number = Number::withCurrency('GBP', function () {
// ...
});Paths

The app function returns the service container instance:
$container = app();You may pass a class or interface name to resolve it from the container:
$api = app('HelpSpot\API');auth()
The auth function returns an authenticator instance. You may use it as an alternative to the Auth facade:
$user = auth()->user();If needed, you may specify which guard instance you would like to access:
$user = auth('admin')->user();bcrypt()
The bcrypt function hashes the given value using Bcrypt. You may use this function as an alternative to the Hash facade:
$password = bcrypt('my-secret-password');blank()
The blank function determines whether the given value is "blank":
blank('');
blank(' ');
blank(null);
blank(collect());
// true
blank(0);
blank(true);
blank(false);
// falseFor the inverse of blank, see the filled function.
cache()
The cache function may be used to get values from the cache. If the given key does not exist in the cache, an optional default value will be returned:
$value = cache('key');
$value = cache('key', 'default');You may add items to the cache by passing an array of key / value pairs to the function. You should also pass the number of seconds or duration the cached value should be considered valid:
cache(['key' => 'value'], 300);
cache(['key' => 'value'], now()->addSeconds(10));class_uses_recursive()
The class_uses_recursive function returns all traits used by a class, including traits used by all of its parent classes:
$traits = class_uses_recursive(App\Models\User::class);collect()
The collect function creates a collection instance from the given value:
$collection = collect(['Taylor', 'Abigail']);config()
The config function gets the value of a configuration variable. The configuration values may be accessed using "dot" syntax, which includes the name of the file and the option you wish to access. You may also provide a default value that will be returned if the configuration option does not exist:
$value = config('app.timezone');
$value = config('app.timezone', $default);You may set configuration variables at runtime by passing an array of key / value pairs. However, note that this function only affects the configuration value for the current request and does not update your actual configuration values:
config(['app.debug' => true]);context()
The context function gets the value from the current context. You may also provide a default value that will be returned if the context key does not exist:
$value = context('trace_id');
$value = context('trace_id', $default);You may set context values by passing an array of key / value pairs:
use LaraGram\Support\Str;
context(['trace_id' => Str::uuid()->toString()]);decrypt()
The decrypt function decrypts the given value. You may use this function as an alternative to the Crypt facade:
$password = decrypt($value);For the inverse of decrypt, see the encrypt function.
dispatch()
The dispatch function pushes the given job onto the LaraGram job queue:
dispatch(new App\Jobs\SendEmails);dispatch_sync()
The dispatch_sync function pushes the given job to the sync queue so that it is processed immediately:
dispatch_sync(new App\Jobs\SendEmails);If you want to stop executing the script after dumping the variables, use the dd function instead.
encrypt()
The encrypt function encrypts the given value. You may use this function as an alternative to the Crypt facade:
$secret = encrypt('my-secret-value');For the inverse of encrypt, see the decrypt function.
env()
The env function retrieves the value of an environment variable or returns a default value:
$env = env('APP_ENV');
$env = env('APP_ENV', 'production');WARNING
If you execute the config:cache command during your deployment process, you should be sure that you are only calling the env function from within your configuration files. Once the configuration has been cached, the .env file will not be loaded and all calls to the env function will return external environment variables such as server-level or system-level environment variables or null.
event()
The event function dispatches the given event to its listeners:
event(new UserRegistered($user));filled()
The filled function determines whether the given value is not "blank":
filled(0);
filled(true);
filled(false);
// true
filled('');
filled(' ');
filled(null);
filled(collect());
// falseFor the inverse of filled, see the blank function.
info()
The info function will write information to your application's log:
info('Some helpful information!');An array of contextual data may also be passed to the function:
info('User login attempt failed.', ['id' => $user->id]);literal()
The literal function creates a new stdClass instance with the given named arguments as properties:
$obj = literal(
name: 'Joe',
languages: ['PHP', 'Ruby'],
);
$obj->name; // 'Joe'
$obj->languages; // ['PHP', 'Ruby']logger()
The logger function can be used to write a debug level message to the log:
logger('Debug message');An array of contextual data may also be passed to the function:
logger('User has logged in.', ['id' => $user->id]);A logger instance will be returned if no value is passed to the function:
logger()->error('You are not allowed here.');now()
The now function creates a new LaraGram\Support\Tempora instance for the current time:
$now = now();once()
The once function executes the given callback and caches the result in memory for the duration of the request. Any subsequent calls to the once function with the same callback will return the previously cached result:
function random(): int
{
return once(function () {
return random_int(1, 1000);
});
}
random(); // 123
random(); // 123 (cached result)
random(); // 123 (cached result)When the once function is executed from within an object instance, the cached result will be unique to that object instance:
<?php
class NumberService
{
public function all(): array
{
return once(fn () => [1, 2, 3]);
}
}
$service = new NumberService;
$service->all();
$service->all(); // (cached result)
$secondService = new NumberService;
$secondService->all();
$secondService->all(); // (cached result)optional()
The optional function accepts any argument and allows you to access properties or call methods on that object. If the given object is null, properties and methods will return null instead of causing an error:
return optional($user->address)->street;
{!! old('name', optional($user)->name) !!}The optional function also accepts a closure as its second argument. The closure will be invoked if the value provided as the first argument is not null:
return optional(User::find($id), function (User $user) {
return $user->name;
});policy()
The policy method retrieves a policy instance for a given class:
$policy = policy(App\Models\User::class);redirect()
The redirect function returns a redirect, or returns the redirector instance if called with no arguments:
return redirect();
return redirect()->listen('listen.name');report()
The report function will report an exception using your exception handler:
report($e);The report function also accepts a string as an argument. When a string is given to the function, the function will create an exception with the given string as its message:
report('Something went wrong.');report_if()
The report_if function will report an exception using your exception handler if a given boolean expression evaluates to true:
report_if($shouldReport, $e);
report_if($shouldReport, 'Something went wrong.');report_unless()
The report_unless function will report an exception using your exception handler if a given boolean expression evaluates to false:
report_unless($reportingDisabled, $e);
report_unless($reportingDisabled, 'Something went wrong.');request()
The request function returns the current request instance or obtains an input field's value from the current request:
$request = request();
$value = request('key', $default);rescue()
The rescue function executes the given closure and catches any exceptions that occur during its execution. All exceptions that are caught will be sent to your exception handler; however, the request will continue processing:
return rescue(function () {
return $this->method();
});You may also pass a second argument to the rescue function. This argument will be the "default" value that should be returned if an exception occurs while executing the closure:
return rescue(function () {
return $this->method();
}, false);
return rescue(function () {
return $this->method();
}, function () {
return $this->failure();
});A report argument may be provided to the rescue function to determine if the exception should be reported via the report function:
return rescue(function () {
return $this->method();
}, report: function (Throwable $throwable) {
return $throwable instanceof InvalidArgumentException;
});resolve()
The resolve function resolves a given class or interface name to an instance using the service container:
$api = resolve('HelpSpot\API');retry()
The retry function attempts to execute the given callback until the given maximum attempt threshold is met. If the callback does not throw an exception, its return value will be returned. If the callback throws an exception, it will automatically be retried. If the maximum attempt count is exceeded, the exception will be thrown:
return retry(5, function () {
// Attempt 5 times while resting 100ms between attempts...
}, 100);If you would like to manually calculate the number of milliseconds to sleep between attempts, you may pass a closure as the third argument to the retry function:
use Exception;
return retry(5, function () {
// ...
}, function (int $attempt, Exception $exception) {
return $attempt * 100;
});For convenience, you may provide an array as the first argument to the retry function. This array will be used to determine how many milliseconds to sleep between subsequent attempts:
return retry([100, 200], function () {
// Sleep for 100ms on first retry, 200ms on second retry...
});To only retry under specific conditions, you may pass a closure as the fourth argument to the retry function:
use App\Exceptions\TemporaryException;
use Exception;
return retry(5, function () {
// ...
}, 100, function (Exception $exception) {
return $exception instanceof TemporaryException;
});tap()
The tap function accepts two arguments: an arbitrary $value and a closure. The $value will be passed to the closure and then be returned by the tap function. The return value of the closure is irrelevant:
$user = tap(User::first(), function (User $user) {
$user->name = 'Taylor';
$user->save();
});If no closure is passed to the tap function, you may call any method on the given $value. The return value of the method you call will always be $value, regardless of what the method actually returns in its definition. For example, the Eloquent update method typically returns an integer. However, we can force the method to return the model itself by chaining the update method call through the tap function:
$user = tap($user)->update([
'name' => $name,
'email' => $email,
]);To add a tap method to a class, you may add the LaraGram\Support\Traits\Tappable trait to the class. The tap method of this trait accepts a Closure as its only argument. The object instance itself will be passed to the Closure and then be returned by the tap method:
return $user->tap(function (User $user) {
// ...
});template()
The template function retrieves a view instance:
return template('panel.admin');throw_if()
The throw_if function throws the given exception if a given boolean expression evaluates to true:
throw_if(! Auth::user()->isAdmin(), AuthorizationException::class);
throw_if(
! Auth::user()->isAdmin(),
AuthorizationException::class,
'You are not allowed to access this page.'
);throw_unless()
The throw_unless function throws the given exception if a given boolean expression evaluates to false:
throw_unless(Auth::user()->isAdmin(), AuthorizationException::class);
throw_unless(
Auth::user()->isAdmin(),
AuthorizationException::class,
'You are not allowed to access this page.'
);today()
The today function creates a new LaraGram\Support\Carbon instance for the current date:
$today = today();trait_uses_recursive()
The trait_uses_recursive function returns all traits used by a trait:
$traits = trait_uses_recursive(\LaraGram\Notifications\Notifiable::class);transform()
The transform function executes a closure on a given value if the value is not blank and then returns the return value of the closure:
$callback = function (int $value) {
return $value * 2;
};
$result = transform(5, $callback);
// 10A default value or closure may be passed as the third argument to the function. This value will be returned if the given value is blank:
$result = transform(null, $callback, 'The value is blank');
// The value is blankvalidator()
The validator function creates a new validator instance with the given arguments. You may use it as an alternative to the Validator facade:
$validator = validator($data, $rules, $messages);value()
The value function returns the value it is given. However, if you pass a closure to the function, the closure will be executed and its returned value will be returned:
$result = value(true);
// true
$result = value(function () {
return false;
});
// falseAdditional arguments may be passed to the value function. If the first argument is a closure then the additional parameters will be passed to the closure as arguments, otherwise they will be ignored:
$result = value(function (string $name) {
return $name;
}, 'Taylor');
// 'Taylor'with()
The with function returns the value it is given. If a closure is passed as the second argument to the function, the closure will be executed and its returned value will be returned:
$callback = function (mixed $value) {
return is_numeric($value) ? $value * 2 : 0;
};
$result = with(5, $callback);
// 10
$result = with(null, $callback);
// 0
$result = with(5, null);
// 5when()
The when function returns the value it is given if a given condition evaluates to true. Otherwise, null is returned. If a closure is passed as the second argument to the function, the closure will be executed and its returned value will be returned:
$value = when(true, 'Hello World');
$value = when(true, fn () => 'Hello World');The when function is primarily useful for conditionally rendering HTML attributes:
<div {!! when($condition, 'wire:poll="calculate"') !!}>
...
</div>Other Utilities
Benchmarking
Sometimes you may wish to quickly test the performance of certain parts of your application. On those occasions, you may utilize the Benchmark support class to measure the number of milliseconds it takes for the given callbacks to complete:
<?php
use App\Models\User;
use LaraGram\Support\Benchmark;
Benchmark::mesure(fn () => User::find(1)); // 0.1 ms
Benchmark::mesure([
'Scenario 1' => fn () => User::count(), // 0.5 ms
'Scenario 2' => fn () => User::all()->count(), // 20.0 ms
]);By default, the given callbacks will be executed once (one iteration), and their duration will be displayed in the browser / console.
To invoke a callback more than once, you may specify the number of iterations that the callback should be invoked as the second argument to the method. When executing a callback more than once, the Benchmark class will return the average number of milliseconds it took to execute the callback across all iterations:
Benchmark::mesure(fn () => User::count(), iterations: 10); // 0.5 msSometimes, you may want to benchmark the execution of a callback while still obtaining the value returned by the callback. The value method will return a tuple containing the value returned by the callback and the number of milliseconds it took to execute the callback:
[$count, $duration] = Benchmark::value(fn () => User::count());Dates
LaraGram includes Tempora, a rewritten version of Carbon, a powerful date and time manipulation library. To create a new Carbon instance, you may invoke the now function. This function is globally available within your LaraGram application:
$now = now();Or, you may create a new Tempora instance using the LaraGram\Support\Tempora class:
use LaraGram\Support\Tempora;
$now = Tempora::now();For a thorough discussion of Carbon and its features, please consult the official Carbon documentation.
Deferred Functions
While LaraGram's queued jobs allow you to queue tasks for background processing, sometimes you may have simple tasks you would like to defer without configuring or maintaining a long-running queue worker.
Deferred functions allow you to defer the execution of a closure until after the HTTP response has been sent to the user, keeping your application feeling fast and responsive. To defer the execution of a closure, simply pass the closure to the LaraGram\Support\defer function:
use App\Services\Metrics;
use LaraGram\Request\Request;
use LaraGram\Support\Facades\Bot;
use function LaraGram\Support\defer;
Bot::onText('orders', function (Request $request) {
// Create order...
defer(fn () => Metrics::reportOrder($order));
return $order;
});By default, deferred functions will only be executed if the HTTP response, Commander command, or queued job from which LaraGram\Support\defer is invoked completes successfully. This means that deferred functions will not be executed if a request results in a 4xx or 5xx HTTP response. If you would like a deferred function to always execute, you may chain the always method onto your deferred function:
defer(fn () => Metrics::reportOrder($order))->always();Cancelling Deferred Functions
If you need to cancel a deferred function before it is executed, you can use the forget method to cancel the function by its name. To name a deferred function, provide a second argument to the LaraGram\Support\defer function:
defer(fn () => Metrics::report(), 'reportMetrics');
defer()->forget('reportMetrics');Lottery
LaraGram's lottery class may be used to execute callbacks based on a set of given odds. This can be particularly useful when you only want to execute code for a percentage of your incoming requests:
use LaraGram\Support\Lottery;
Lottery::odds(1, 20)
->winner(fn () => $user->won())
->loser(fn () => $user->lost())
->choose();You may combine LaraGram's lottery class with other LaraGram features. For example, you may wish to only report a small percentage of slow queries to your exception handler. And, since the lottery class is callable, we may pass an instance of the class into any method that accepts callables:
use Carbon\CarbonInterval;
use LaraGram\Support\Facades\DB;
use LaraGram\Support\Lottery;

);Pipeline
LaraGram's Pipeline facade provides a convenient way to "pipe" a given input through a series of invokable classes, closures, or callables, giving each class the opportunity to inspect or modify the input and invoke the next callable in the pipeline:
use Closure;
use App\Models\User;
use LaraGram\Support\Facades\Pipeline;
$user = Pipeline::send($user)
->through([
function (User $user, Closure $next) {
// ...
return $next($user);
},
function (User $user, Closure $next) {
// ...
return $next($user);
},
])
->then(fn (User $user) => $user);As you can see, each invokable class or closure in the pipeline is provided the input and a $next closure. Invoking the $next closure will invoke the next callable in the pipeline. As you may have noticed, this is very similar to middleware.
When the last callable in the pipeline invokes the $next closure, the callable provided to the then method will be invoked. Typically, this callable will simply return the given input. For convenience, if you simply want to return the input after it has been processed, you may use the thenReturn method.
Of course, as discussed previously, you are not limited to providing closures to your pipeline. You may also provide invokable classes. If a class name is provided, the class will be instantiated via LaraGram's service container, allowing dependencies to be injected into the invokable class:
$user = Pipeline::send($user)
->through([
GenerateProfilePhoto::class,
ActivateSubscription::class,
SendWelcomeEmail::class,
])
->thenReturn();Sleep
LaraGram's Sleep class is a light-weight wrapper around PHP's native sleep and usleep functions, offering greater testability while also exposing a developer friendly API for working with time:
use LaraGram\Support\Sleep;
$waiting = true;
while ($waiting) {
Sleep::for(1)->second();
$waiting = /* ... */;
}The Sleep class offers a variety of methods that allow you to work with different units of time:
// Return a value after sleeping...
$result = Sleep::for(1)->second()->then(fn () => 1 + 1);
// Sleep while a given value is true...
Sleep::for(1)->second()->while(fn () => shouldKeepSleeping());
// Pause execution for 90 seconds...
Sleep::for(1.5)->minutes();
// Pause execution for 2 seconds...
Sleep::for(2)->seconds();
// Pause execution for 500 milliseconds...
Sleep::for(500)->milliseconds();
// Pause execution for 5,000 microseconds...
Sleep::for(5000)->microseconds();
// Pause execution until a given time...
Sleep::until(now()->addMinute());
// Alias of PHP's native "sleep" function...
Sleep::sleep(2);
// Alias of PHP's native "usleep" function...
Sleep::usleep(5000);To easily combine units of time, you may use the and method:
Sleep::for(1)->second()->and(10)->milliseconds();Timebox
LaraGram's Timebox class ensures that the given callback always takes a fixed amount of time to execute, even if its actual execution completes sooner. This is particularly useful for cryptographic operations and user authentication checks, where attackers might exploit variations in execution time to infer sensitive information.
If the execution exceeds the fixed duration, Timebox has no effect. It is up to the developer to choose a sufficiently long time as the fixed duration to account for worst-case scenarios.
The call method accepts a closure and a time limit in microseconds, and then executes the closure and waits until the time limit is reached:
use LaraGram\Support\Timebox;
(new Timebox)->call(function ($timebox) {
// ...
}, microseconds: 10000);If an exception is thrown within the closure, this class will respect the defined delay and re-throw the exception after the delay.
