README
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() }
