Purpose

This package was inspired by some of the great array helper functions in Laravel.

Having to include all of Illuminate\Support is sometimes a bit too much for a given project, so I decided to build a separate package to provide some much needed framework independent array magic.

Installation

Installation can be done easily through composer.

composer require jdrieghe/array-helpers

Usage

Static approach

You can choose to use only the static helper methods.

use ArrayHelpers\Arr;

$result = Arr::get($array, $key, $default);

Functional approach

If you prefer a more functional approach, some namespaced convenience methods are available as well:

use function ArrayHelpers\array_get;

$result = array_get($array, $key, $default);

Available helpers

Array Get

This helper allows you to get an item from an array using dot notation. If the item is not found, it will return a given default or null.

$data = [
    'foo' => [
        'bar' => 'baz',
    ],
];

Arr::get($data, 'foo');
// returns: ['bar' => 'baz'];
 
Arr::get($data, 'foo.bar'); 
// returns: 'baz';

Arr::get($data, 'xyz', 'default');
// returns: 'default';

Note that Arr::get() can be replaced with array_get() if you prefer a functional approach.

Array Has

This helper checks if an item exists in an array using dot notation.

$data = [
    'foo' => [
        'bar' => 'baz',
    ],
];

Arr::has($data, 'foo');
// returns: true;
 
Arr::has($data, 'foo.bar'); 
// returns: true;

Arr::has($data, 'xyz');
// returns: false;

Note that Arr::has() can be replaced with array_has() if you prefer a functional approach.

Array Set

This helper sets a certain key in an array to a certain value. Dot notation can be used to create a deeply nested key.

$data = [];
Arr::set($data, 'foo.bar', 'baz');

$data now contains:

[
    'foo' => [
        'bar' => 'baz',
    ],
]; 

Note that Arr::set() can be replaced with array_set() if you prefer a functional approach.
