jdrieghe/array-helpers

A collection of convenience methods to deal with arrays in php.

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.
