Array

The array library is just a simple collection of missing php array functions.

Installation

Install with composer at krak/array

Usage

<?php

use Krak\Arr;

$data = [
    'a' => [
        'b' => 1,
    ],
];

$res = Arr\get($data, 'a.b');
assert($res == 1);

Arr\set($data, 'c.d', 2);
assert($data['c']['d'] == 2);

// or use the global aliases
array_get($data, 'a.b');

There also is a Bag class which provides an object oriented API for the arrays.

<?php

use Krak\Arr;

$bag = new Arr\Bag();
$bag->set('a.b', 1);
var_dump($bag->raw());
/*
    array(1) {
      ["a"]=>
      array(1) {
        ["b"]=>
        int(1)
      }
    }
*/

API

The following are defined in the namespace Krak\Arr:

array expand(iterable $iterable, string $separator = '.')
array index_by(iterable $iterable, string $key)
array udiff_stable(iterable $a, iterable $b, callable $cmp)
mixed get(array $data, string $key, mixed $else = null)
mixed getIn(array $data, array $key, mixed $else = null);
bool has(array $data, string $key, string $sep = '.')
bool hasIn(array $data, array $key)
void set(array &$data, string $key, mixed $value, string $sep = '.')
void del(array &$data, string $key, string $sep = '.')

You can also use the globally defined aliases

array_expand
array_index_by
array_udiff_stable
array_get
array_has
array_set
array_del

Or the Krak\Arr\Bag class:

<?php

namespace Krak\Arr;

class Bag implements ArrayAccess {
    public function __construct(array $data = [])
    public function get($key, $else = null, $sep = '.')
    public function getIn(array $key, $else = null)
    public function set($key, $value, $sep = '.')
    public function has($key, $sep = '.')
    public function hasIn(array $key)
    public function del($key, $sep = '.')
    public function raw()
}
