$isAccessible = Arr::accessible('abc');
 
// false
 
$isAccessible = Arr::accessible(new stdClass);
 
// false

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]

/*
    [
        [1, 'a'],
        [1, 'b'],
        [2, 'a'],
        [2, 'b'],

// $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;

$first = Arr::first($array, function ($value, $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:

$discount = Arr::get($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

Arr::hasAny()

The Arr::hasAny method checks whether any item in a given set exists in an array using "dot" notation:

use Illuminate\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']);
 
// false

Arr::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 Illuminate\Support\Arr;
 
$isAssoc = Arr::isAssoc(['product' => ['name' => 'Desk', 'price' => 100]]);
 
// true
 
$isAssoc = Arr::isAssoc([1, 2, 3]);

// true
 
$isList = Arr::isList(['product' => ['name' => 'Desk', 'price' => 100]]);
 
// false

Arr::join()

The Arr::join method joins array elements with a string. Using this method's second argument, you may also specify the joining string for the final element of the array:

use Illuminate\Support\Arr;
 
$array = ['Tailwind', 'Alpine', 'Laravel', 'Livewire'];
 
$joined = Arr::join($array, ', ');
 
// Tailwind, Alpine, Laravel, Livewire
 
$joined = Arr::join($array, ', ', ' and ');
 
// Tailwind, Alpine, Laravel and Livewire

Arr::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 Illuminate\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'],
    ]
*/

    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 ($value, $key) {
    return ucfirst($value);
});
 
// ['first' => 'James', 'last' => 'Kirk']

Arr::only()

The Arr::only method returns only the specified key / value pairs from the given array:

use Illuminate\Support\Arr;
 
$array = ['name' => 'Desk', 'price' => 100, 'orders' => 10];
 
$slice = Arr::only($array, ['name', 'price']);
 
// ['name' => 'Desk', 'price' => 100]

Arr::pluck()

use Illuminate\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:

$array = Arr::prepend($array, 'zero');
 
// ['zero', 'one', 'two', 'three', 'four']

If needed, you may specify the key that should be used for the value:

use Illuminate\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 Illuminate\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 Illuminate\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 Illuminate\Support\Arr;
 
$value = Arr::pull($array, $key, $default);

Arr::query()

The Arr::query method converts the array into a query string:

use Illuminate\Support\Arr;
 
$array = [
    'name' => 'Taylor',
    'order' => [
        'column' => 'created_at',

// name=Taylor&order[column]=created_at&order[direction]=desc

Arr::random()

The Arr::random method returns a random value from an array:

use Illuminate\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 Illuminate\Support\Arr;
 
$items = Arr::random($array, 2);
 
// [2, 5] - (retrieved randomly)

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:

use Illuminate\Support\Arr;
 
$array = Arr::shuffle([1, 2, 3, 4, 5]);
 
// [3, 2, 5, 1, 4] - (generated randomly)

Arr::sort()

The Arr::sort method sorts an array by its values:

use Illuminate\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 Illuminate\Support\Arr;
 
$array = [
    ['name' => 'Desk'],
    ['name' => 'Table'],
    ['name' => 'Chair'],
];
 
$sorted = array_values(Arr::sort($array, function ($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 Illuminate\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 Illuminate\Support\Arr;
 
$array = [
    ['name' => 'Desk'],
    ['name' => 'Table'],
    ['name' => 'Chair'],
];
 
$sorted = array_values(Arr::sortDesc($array, function ($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 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 Blade directive.

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()

The Arr::where method filters an array using the given closure:

use Illuminate\Support\Arr;
 
$array = [100, '200', 300, '400', 500];
 
$filtered = Arr::where($array, function ($value, $key) {
    return is_string($value);
});
 
// [1 => '200', 3 => '400']

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()

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 Illuminate\Support\Arr;
 
$string = 'Laravel';
 
$array = Arr::wrap($string);
 
// ['Laravel']

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:

$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');
 
// 100

The 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);
 
// 0

The 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'];

data_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]]]

$array = [100, 200, 300];
 
$first = head($array);
 
// 100

last()
