Introduction

Laravel 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.

Arr::accessible()

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

 1use Illuminate\Support\Arr;
 2use Illuminate\Support\Collection;
 3 
 4$isAccessible = Arr::accessible(['a' => 1, 'b' => 2]);
 5 
 6// true
 7 
 8$isAccessible = Arr::accessible(new Collection);
 9 
10// true
11 
12$isAccessible = Arr::accessible('abc');
13 
14// false
15 
16$isAccessible = Arr::accessible(new stdClass);
17 
18// false
 1use Illuminate\Support\Arr;

 3 
 4$isAccessible = Arr::accessible(['a' => 1, 'b' => 2]);

18// 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:

 3$array = ['Tailwind', 'Alpine', 'Laravel', 'Livewire'];
 4 
 5$joined = Arr::join($array, ', ');
 6 
 7// Tailwind, Alpine, Laravel, Livewire

11// 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:

 1use Illuminate\Support\Arr;
 2 
 3$array = [
 4    ['product_id' => 'prod-100', 'name' => 'Desk'],
 5    ['product_id' => 'prod-200', 'name' => 'Chair'],

 9 
10/*
11    [
12        'prod-100' => ['product_id' => 'prod-100', 'name' => 'Desk'],

4 
5$last = Arr::last($array, function ($value, $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;
2 
3$array = ['name' => 'Desk', 'price' => 100, 'orders' => 10];
4 
5$slice = Arr::only($array, ['name', 'price']);
6 
7// ['name' => 'Desk', 'price' => 100]

Arr::pluck()

The Arr::pluck method retrieves all of the values for a given key from an array:

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

4 
5// [3, 2, 5, 1, 4] - (generated randomly)

Arr::sort()

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

1use Illuminate\Support\Arr;

 1use Illuminate\Support\Arr;
 2 
 3$array = [
 4    ['Roman', 'Taylor', 'Li'],
 5    ['PHP', 'Ruby', 'JavaScript'],
 6    ['one' => 1, 'two' => 2, 'three' => 3],
 7];
 8 
 9$sorted = Arr::sortRecursive($array);
10 
11/*
12    [
13        ['JavaScript', 'PHP', 'Ruby'],
14        ['one' => 1, 'three' => 3, 'two' => 2],
15        ['Li', 'Roman', 'Taylor'],

15        ['Li', 'Roman', 'Taylor'],
16    ]
17*/

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:

 1use Illuminate\Support\Arr;
 2 
 3$isActive = false;
 4$hasError = true;
 5 
 6$array = ['p-4', 'font-bold' => $isActive, 'bg-red' => $hasError];
 7 
 8$classes = Arr::toCssClasses($array);
 9 
10/*
11    'p-4 bg-red'
12*/
 1use Illuminate\Support\Arr;
 2 
 3$isActive = false;
 4$hasError = true;
 5 
 6$array = ['p-4', 'font-bold' => $isActive, 'bg-red' => $hasError];
 7 
 8$classes = Arr::toCssClasses($array);
 9 
10/*
11    'p-4 bg-red'
12*/

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:

 1use Illuminate\Support\Arr;

 9 
10// ['user' => ['name' => 'Kevin Malone', 'occupation' => 'Accountant']]
 1use Illuminate\Support\Arr;
 2 
 3$array = [
 4    'user.name' => 'Kevin Malone',
 5    'user.occupation' => 'Accountant',

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

Arr::whereNotNull()

4 
5$filtered = Arr::whereNotNull($array);
6 
7// [0 => 0]
1use Illuminate\Support\Arr;
2 
3$array = [0, null];
4 
5$filtered = Arr::whereNotNull($array);
6 
7// [0 => 0]

Arr::wrap()

Str::betweenFirst()

The Str::betweenFirst method returns the smallest possible portion of a string between two values:

1use Illuminate\Support\Str;
2 
3$slice = Str::betweenFirst('[a] bc [d]', '[', ']');
4 
5// 'a'
1use Illuminate\Support\Str;
2 
3$slice = Str::betweenFirst('[a] bc [d]', '[', ']');
4 
5// 'a'

Str::camel()

The Str::camel method converts the given string to camelCase:

1use Illuminate\Support\Str;
2 
3$converted = Str::camel('foo_bar');
4 
5// fooBar
1use Illuminate\Support\Str;
2 
3$converted = Str::camel('foo_bar');
4 
5// fooBar

Str::contains()

The Str::contains method determines if the given string contains the given value. This method is case sensitive:

1use Illuminate\Support\Str;
2 
3$contains = Str::contains('This is my name', 'my');
4 
5// true
1use Illuminate\Support\Str;
2 
3$contains = Str::contains('This is my name', 'my');
4 
5// true

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

1use Illuminate\Support\Str;
2 
3$contains = Str::contains('This is my name', ['my', 'foo']);
4 
5// true
1use Illuminate\Support\Str;
2 
3$contains = Str::contains('This is my name', ['my', 'foo']);
4 
5// true

Str::containsAll()

The Str::containsAll method determines if the given string contains all of the values in a given array:

1use Illuminate\Support\Str;
2 
3$containsAll = Str::containsAll('This is my name', ['my', 'name']);
4 
5// true
1use Illuminate\Support\Str;
2 
3$containsAll = Str::containsAll('This is my name', ['my', 'name']);
4 
5// true

Str::endsWith()

The Str::endsWith method determines if the given string ends with the given value:

1use Illuminate\Support\Str;
2 
3$result = Str::endsWith('This is my name', 'name');
4 
5// true
1use Illuminate\Support\Str;
2 
3$result = Str::endsWith('This is my name', 'name');
4 
5// true

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

1use Illuminate\Support\Str;
2 
3$result = Str::endsWith('This is my name', ['name', 'foo']);
4 
5// true
6 
7$result = Str::endsWith('This is my name', ['this', 'foo']);
8 
9// false
1use Illuminate\Support\Str;
2 
3$result = Str::endsWith('This is my name', ['name', 'foo']);
4 
5// true
6 
7$result = Str::endsWith('This is my name', ['this', 'foo']);
8 
9// false

Str::excerpt()

The Str::excerpt method extracts an excerpt from a given string that matches the first instance of a phrase within that string:

1use Illuminate\Support\Str;
2 
3$excerpt = Str::excerpt('This is my name', 'my', [
4    'radius' => 3
5]);
6 
7// '...is my na...'
1use Illuminate\Support\Str;
2 
3$excerpt = Str::excerpt('This is my name', 'my', [
4    'radius' => 3
5]);
6 
7// '...is my na...'

The radius option, which defaults to 100, allows you to define the number of characters that should appear on each side of the truncated string.

In addition, you may use the omission option to define the string that will be prepended and appended to the truncated string:

1use Illuminate\Support\Str;
2 
3$excerpt = Str::excerpt('This is my name', 'name', [
4    'radius' => 3,
5    'omission' => '(...) '
6]);
7 
8// '(...) my name'
1use Illuminate\Support\Str;
2 
3$excerpt = Str::excerpt('This is my name', 'name', [
4    'radius' => 3,
5    'omission' => '(...) '
6]);
7 
8// '(...) my name'
