4 
5$last = Arr::last($array, function (int $value, int $key) {
6    return $value >= 150;
7});
8 
9// 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:

1use Illuminate\Support\Arr;

11$mapped = Arr::mapSpread($array, function (int $even, int $odd) {
12    return $even + $odd;
13});
14 
15/*
16    [1, 5, 9, 13, 17]

13    ]
14];
15 
16$mapped = Arr::mapWithKeys($array, function (array $item, int $key) {
17    return [$item['email'] => $item['name']];
18});
19

Arr::pull()

The Arr::pull method returns and removes a key / value pair from an array:

1use Illuminate\Support\Arr;
2 
3$array = ['name' => 'Desk', 'price' => 100];
4 
5$name = Arr::pull($array, 'name');
6 
7// $name: Desk

4 
5$name = Arr::pull($array, 'name');
6 
7// $name: Desk
8 
9// $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:

1use Illuminate\Support\Arr;

If you would like the results sorted in descending order, you may use the Arr::sortRecursiveDesc method.

1$sorted = Arr::sortRecursiveDesc($array);
1$sorted = Arr::sortRecursiveDesc($array);

Arr::take()

The Arr::take method returns a new array with the specified number of items:

1use Illuminate\Support\Arr;

3$array = [0, 1, 2, 3, 4, 5];
4 
5$chunk = Arr::take($array, 3);
6 
7// [0, 1, 2]

You may also pass a negative integer to take the specified number of items from the end of the array:

1$array = [0, 1, 2, 3, 4, 5];
2 
3$chunk = Arr::take($array, -2);
4 
5// [4, 5]
1$array = [0, 1, 2, 3, 4, 5];
2 
3$chunk = Arr::take($array, -2);
4 
5// [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:

 1use Illuminate\Support\Arr;
 2 
 3$isActive = false;
 4$hasError = true;
 5 
 6$array = ['p-4', 'font-bold' => $isActive, 'bg-red' => $hasError];

 9 
10/*
11    'p-4 bg-red'
12*/

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:

 1use Illuminate\Support\Arr;
 2 
 3$hasColor = true;
 4 
 5$array = ['background-color: blue', 'color: blue' => $hasColor];
 6 
 7$classes = Arr::toCssStyles($array);
 8 
 9/*
10    'background-color: blue; color: blue;'
11*/
 1use Illuminate\Support\Arr;
 2 
 3$hasColor = true;
 4 
 5$array = ['background-color: blue', 'color: blue' => $hasColor];
 6 
 7$classes = Arr::toCssStyles($array);
 8 
 9/*
10    'background-color: blue; color: blue;'
11*/

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()

1use Illuminate\Support\Arr;
2 
3$array = [100, '200', 300, '400', 500];
4 
5$filtered = Arr::where($array, function (string|int $value, int $key) {
6    return is_string($value);
7});
8 
9// [1 => '200', 3 => '400']

Arr::whereNotNull()

4 
5$filtered = Arr::whereNotNull($array);
6 
7// [0 => 0]

Arr::wrap()

6 
7// ['Laravel']
1use Illuminate\Support\Arr;
2 
3$string = 'Laravel';
4 
5$array = Arr::wrap($string);

 1use Illuminate\Support\Number;
 2 
 3$number = Number::clamp(105, min: 10, max: 100);
 4 
 5// 100
 6 
 7$number = Number::clamp(5, min: 10, max: 100);
 8 
 9// 10
10 
11$number = Number::clamp(10, min: 10, max: 100);
12 
13// 10
14 
15$number = Number::clamp(20, min: 10, max: 100);
16 
17// 20
 1use Illuminate\Support\Number;
 2 
 3$number = Number::clamp(105, min: 10, max: 100);
