Method Listing

Arr::accessible()

The Arr::accessible method determines if the given value is array accessible:

Arr::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 Illuminate\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::collapse()

The Arr::collapse method collapses an array of arrays into a single array:

use Illuminate\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 Illuminate\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 Illuminate\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 Illuminate\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 Illuminate\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:

Arr::first()

The Arr::first method returns the first element of an array passing a given truth test:

use Illuminate\Support\Arr; $array = [100, 200, 300]; $first = Arr::first($array, function (int $value, int $key) {    return $value >= 150;}); // 200

A 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 Illuminate\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 Illuminate\Support\Arr; $array = ['name' => 'Joe', 'languages' => ['PHP', 'Ruby']]; $flattened = Arr::flatten($array); // ['Joe', 'PHP', 'Ruby']

Arr::forget()

use Illuminate\Support\Arr; $array = ['products' => ['desk' => ['price' => 100]]]; $price = Arr::get($array, 'products.desk.price'); // 100

The Arr::get method also accepts a default value, which will be returned if the specified key is not present in the array:

use Illuminate\Support\Arr; $discount = Arr::get($array, 'products.desk.discount', 0); // 0

Arr::has()

The Arr::has method checks whether a given item or items exists in an array using “dot” notation:

use Illuminate\Support\Arr; $array = ['product' => ['name' => 'Desk', 'price' => 100]]; $contains = Arr::has($array, 'product.name'); // true $contains = Arr::has($array, ['product.price', 'product.discount']); // false

The Arr::last method returns the last element of an array passing a given truth test:

use Illuminate\Support\Arr; $array = [100, 200, 300, 110]; $last = Arr::last($array, function (int $value, int $key) {    return $value >= 150;}); // 300

A 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 Illuminate\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 Illuminate\Support\Arr; $array = ['first' => 'james', 'last' => 'kirk']; $mapped = Arr::map($array, function (string $value, string $key) {    return ucfirst($value);}); // ['first' => 'James', 'last' => 'Kirk']

Arr::set()

The Arr::set method sets a value within a deeply nested array using “dot” notation:

use Illuminate\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:

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 Illuminate\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'],    ]*/

Arr::toCssClasses()

The Arr::toCssClasses 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 Illuminate\Support\Arr; $isActive = false;$hasError = true; $array = ['p-4', 'font-bold' => $isActive, 'bg-red' => $hasError]; $classes = Arr::toCssClasses($array); /*    'p-4 bg-red'*/

This method powers Laravel’s functionality allowing merging classes with a Blade component’s attribute bag as well as the @class .

Arr::undot()

The Arr::undot method expands a single-dimensional array that uses “dot” notation into a multi-dimensional array:

use Illuminate\Support\Arr; $array = [    'user.name' => 'Kevin Malone',    'user.occupation' => 'Accountant',]; $array = Arr::undot($array); // ['user' => ['name' => 'Kevin Malone', 'occupation' => 'Accountant']]

Arr::where()

Arr::whereNotNull()

The Arr::whereNotNull method removes all null values from the given array:

use Illuminate\Support\Arr; $array = [0, null]; $filtered = Arr::whereNotNull($array); // [0 => 0]

Arr::wrap()

If the given value is null, an empty array will be returned:

use Illuminate\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:

use Illuminate\Support\Str; $string = Str::of('Tacos are great!')    ->swap([        'Tacos' => 'Burritos',        'great' => 'fantastic',    ]); // Burritos are fantastic!

tap

The tap method passes the string to the given closure, allowing you to examine and interact with the string while not affecting the string itself. The original string is returned by the tap method regardless of what is returned by the closure:

use Illuminate\Support\Str;use Illuminate\Support\Stringable; $string = Str::of('Laravel')    ->append(' Framework')    ->tap(function (Stringable $string) {        dump('String after append: '.$string);    })    ->upper(); // LARAVEL FRAMEWORK

test

The test method determines if a string matches the given regular expression pattern:

use Illuminate\Support\Str; $result = Str::of('Laravel Framework')->test('/Laravel/'); // true

title

The title method converts the given string to Title Case:

use Illuminate\Support\Str; $converted = Str::of('a nice title uses the correct case')->title(); // A Nice Title Uses The Correct Case

trim

The trim method trims the given string:

use Illuminate\Support\Str; $string = Str::of('  Laravel  ')->trim(); // 'Laravel' $string = Str::of('/Laravel/')->trim('/'); // 'Laravel'

ucfirst

The ucfirst method returns the given string with the first character capitalized:

use Illuminate\Support\Str; $string = Str::of('foo bar')->ucfirst(); // Foo bar

ucsplit

upper

The upper method converts the given string to uppercase:

use Illuminate\Support\Str; $adjusted = Str::of('laravel')->upper(); // LARAVEL

when

The when method invokes the given closure if a given condition is true. The closure will receive the fluent string instance:

use Illuminate\Support\Str;use Illuminate\Support\Stringable; $string = Str::of('Taylor')                ->when(true, function (Stringable $string) {                    return $string->append(' Otwell');                }); // 'Taylor Otwell'

If necessary, you may pass another closure as the third parameter to the when method. This closure will execute if the condition parameter evaluates to false.

whenContains

The whenContains method invokes the given closure if the string contains the given value. The closure will receive the fluent string instance:

use Illuminate\Support\Str;use Illuminate\Support\Stringable; $string = Str::of('tony stark')            ->whenContains('tony', function (Stringable $string) {                return $string->title();            }); // 'Tony Stark'

If necessary, you may pass another closure as the third parameter to the when method. This closure will execute if the string does not contain the given value.

You may also pass an array of values to determine if the given string contains any of the values in the array:

use Illuminate\Support\Str;use Illuminate\Support\Stringable; $string = Str::of('tony stark')            ->whenContains(['tony', 'hulk'], function (Stringable $string) {                return $string->title();            }); // Tony Stark

whenContainsAll

The whenContainsAll method invokes the given closure if the string contains all of the given sub-strings. The closure will receive the fluent string instance:

use Illuminate\Support\Str;use Illuminate\Support\Stringable; $string = Str::of('tony stark')                ->whenContainsAll(['tony', 'stark'], function (Stringable $string) {                    return $string->title();                }); // 'Tony Stark'

If necessary, you may pass another closure as the third parameter to the when method. This closure will execute if the condition parameter evaluates to false.

whenEmpty

The whenEmpty method invokes the given closure if the string is empty. If the closure returns a value, that value will also be returned by the whenEmpty method. If the closure does not return a value, the fluent string instance will be returned:

use Illuminate\Support\Str;use Illuminate\Support\Stringable; $string = Str::of('  ')->whenEmpty(function (Stringable $string) {    return $string->trim()->prepend('Laravel');}); // 'Laravel'

whenNotEmpty

The whenNotEmpty method invokes the given closure if the string is not empty. If the closure returns a value, that value will also be returned by the whenNotEmpty method. If the closure does not return a value, the fluent string instance will be returned:

use Illuminate\Support\Str;use Illuminate\Support\Stringable; $string = Str::of('Framework')->whenNotEmpty(function (Stringable $string) {    return $string->prepend('Laravel ');}); // 'Laravel Framework'

whenStartsWith

The whenStartsWith method invokes the given closure if the string starts with the given sub-string. The closure will receive the fluent string instance:

use Illuminate\Support\Str;use Illuminate\Support\Stringable; $string = Str::of('disney world')->whenStartsWith('disney', function (Stringable $string) {    return $string->title();}); // 'Disney World'
