Installation via "composer require"

composer require voku/arrayy

Installation via composer (manually)

If you're using Composer to manage dependencies, you can include the following in your composer.json file:

"require": {
    "voku/arrayy": "3.*"
}

Then, after running composer update or php composer.phar update, you can load the class using Composer's autoloading:

require 'vendor/autoload.php';

And in either case, I'd suggest using an alias.

use Arrayy\Arrayy as A;

Multidimensional ArrayAccess

You can access / change the array via Object, Array or with "Arrayy"-syntax.

Access via "Arrayy"-syntax: (dot-notation)

-- Recommended --

$arrayy = new A(['Lars' => ['lastname' => 'Moelleken']]);

$arrayy->get('Lars'); // ['lastname' => 'Moelleken']
$arrayy->get('Lars.lastname'); // 'Moelleken'

Access via "array"-syntax:

$arrayy = new A(['Lars' => ['lastname' => 'Moelleken']]);

$arrayy['Lars'];             // ['lastname' => 'Moelleken']
$arrayy['Lars']['lastname']; // 'Moelleken'

Access via "object"-syntax:

$arrayy = new A(['Lars' => ['lastname' => 'Moelleken']]);

$arrayy->Lars; // Arrayy['lastname' => 'Moelleken']
$arrayy->Lars->lastname; // 'Moelleken'

Set values via "Arrayy"-syntax: (dot-notation)

-- Recommended --

$arrayy = new A(['Lars' => ['lastname' => 'Mueller']]);

$arrayy->set('Lars.lastname', 'Moelleken');
$arrayy->get('Lars.lastname'); // 'Moelleken'

Set values via "array"-syntax:

$arrayy = new A(['Lars' => ['lastname' => 'Moelleken']]);

$arrayy['Lars'] = array('lastname' => 'Müller');
$arrayy['Lars']['lastname]; // 'Müller'

Set values via "object"-syntax:

$arrayy = new A(['Lars' => ['lastname' => 'Moelleken']]);

$arrayy->Lars = array('lastname' => 'Müller');
$arrayy->Lars->lastname; // 'Müller'

OO and Chaining

The library offers OO method chaining, as seen below:

echo a(['fòô', 'bàř', 'bàř'])->unique()->reverse()->implode(','); // 'bàř,fòô'

Implemented Interfaces

Arrayy\Arrayy implements the IteratorAggregate interface, meaning that foreach can be used with an instance of the class:

$arrayy = a(['fòôbàř', 'foo']);
foreach ($arrayy as $value) {
    echo $value;
}
// 'fòôbàř'
// 'foo'

It implements the Countable interface, enabling the use of count() to retrieve the number of elements in the array:

$arrayy = a(['fòô', 'foo']);
count($arrayy);  // 2

PHP 5.6 Creation

As of PHP 5.6, use function is available for importing functions. Arrayy exposes a namespaced function, Arrayy\create, which emits the same behaviour as Arrayy\Arrayy::create(). If running PHP 5.6, or another runtime that supports the use function syntax, you can take advantage of an even simpler API as seen below:

use function Arrayy\create as a;

// Instead of: A::create(['fòô', 'bàř'])->reverse()->implode();
a(['fòô', 'bàř'])->reverse()->implode(','); // 'bàř,fòô'

StaticArrayy

All methods listed under "Instance methods" are available as part of a static wrapper.

use Arrayy\StaticArrayy as A;

// Translates to Arrayy::create(['fòô', 'bàř'])->reverse();
// Returns an Arrayy object with the array
A::reverse(['fòô', 'bàř']);

Class methods

use a "default object"

Creates an Arrayy object.

$arrayy = new Arrayy(array('fòô', 'bàř')); // Arrayy['fòô', 'bàř']

create(array $array) : Arrayy (Immutable)

Creates an Arrayy object, via static "create()"-method

$arrayy = A::create(array('fòô', 'bàř')); // Arrayy['fòô', 'bàř']

createByReference(array &$array) : Arrayy (Mutable)

WARNING: Creates an Arrayy object by reference.

$array = array('fòô', 'bàř');
$arrayy = A::createByReference($array); // Arrayy['fòô', 'bàř']

createFromJson(string $json) : Arrayy (Immutable)

Create an new Arrayy object via JSON.

$str = '{"firstName":"John", "lastName":"Doe"}';
$arrayy = A::createFromJson($str); // Arrayy['firstName' => 'John', 'lastName' => 'Doe']

createFromObject(ArrayAccess $object) : Arrayy (Immutable)

Create an new instance filled with values from an object that have implemented ArrayAccess.

$object = A::create(1, 'foo');
$arrayy = A::createFromObject($object); // Arrayy[1, 'foo']

createFromObjectVars(\object $object) : Arrayy (Immutable)

Create an new instance filled with values from an object.

$object = new stdClass();
$object->x = 42;
$arrayy = A::createFromObjectVars($object); // Arrayy['x' => 42]

createWithRange() : Arrayy (Immutable)

Create an new instance containing a range of elements.

$arrayy = A::createWithRange(2, 4); // Arrayy[2, 3, 4]

createFromString(string $str) : Arrayy (Immutable)

$arrayy = A::createFromString(' foo, bar '); // Arrayy['foo', 'bar']

rest(int $from) : Arrayy (Immutable)

Get the last elements from index $from until the end of this array.

a([2 => 'foo', 3 => 'bar', 4 => 'lall'])->rest(2); // Arrayy[0 => 'lall']

reverse() : Arrayy (Mutable)

Return the array in the reverse order.

a([1, 2, 3])->reverse(); // self[3, 2, 1]

searchIndex(mixed $value) : mixed

Search for the first index of the current array via $value.

a(['fòô' => 'bàř', 'lall' => 'bàř'])->searchIndex('bàř'); // Arrayy[0 => 'fòô']

searchValue(mixed $index) : Arrayy (Immutable)

Search for the value of the current array via $index.

a(['fòô' => 'bàř'])->searchValue('fòô'); // Arrayy[0 => 'bàř']

set(mixed $key, mixed $value) : Arrayy (Immutable)

Set a value for the current array (optional using dot-notation).

$arrayy = a(['Lars' => ['lastname' => 'Moelleken']]);
$arrayy->set('Lars.lastname', 'Müller'); // Arrayy['Lars', ['lastname' => 'Müller']]]

setAndGet()

Get a value from a array and set it if it was not.

WARNING: this method only set the value, if the $key is not already set

$arrayy = a([1 => 1, 2 => 2, 3 => 3]);
$arrayy->setAndGet(1, 4); // 1
$arrayy->setAndGet(0, 4); // 4

serialize() : string

Serialize the current arrayy-object.

a([1, 4, 7])->serialize();

unserialize(string $string) : Arrayy (Mutable)

Unserialize an string and return this object.

$serialized = a([1, 4, 7])->serialize();
a()->unserialize($serialized);

sort(string|int(SORT_ASC) $direction, int(SORT_REGULAR) $strategy, bool(false) $keepKeys) : Arrayy (Mutable)

Sort the current array and optional you can keep the keys.

$direction e.g.: [SORT_ASC, SORT_DESC, 'ASC', 'asc', 'DESC', 'desc']
$strategy e.g.: [SORT_REGULAR, SORT_NATURAL, ...]

a(3 => 'd', 2 => 'f', 0 => 'a')->sort(SORT_ASC, SORT_NATURAL, false); // Arrayy[0 => 'a', 1 => 'd', 2 => 'f']

sorter(null|callable $sorter, string|int(SORT_ASC) $direction, int(SORT_REGULAR) $strategy) : Arrayy (Immutable)

Sort a array by value, by a closure or by a property.

If the sorter is null (default), the array is sorted naturally.
Associative (string) keys will be maintained, but numeric keys will be re-indexed.
$direction e.g.: [SORT_ASC, SORT_DESC, 'ASC', 'asc', 'DESC', 'desc']
$strategy e.g.: [SORT_REGULAR, SORT_NATURAL, ...]

$testArray = range(1, 5);
$under = a($testArray)->sorter(
  function ($value) {
    return $value % 2 === 0;
  }
);
var_dump($under); // Arrayy[1, 3, 5, 2, 4]

sortKeys(string|int(SORT_ASC) $direction) : Arrayy (Mutable)

Sort the current array by key by $direction = 'asc' or $direction = 'desc'.

$direction e.g.: [SORT_ASC, SORT_DESC, 'ASC', 'asc', 'DESC', 'desc']

a([1 => 2, 0 => 1])->sortKeys('asc'); // Arrayy[0 => 1, 1 => 2]

sortValueNewIndex(string|int(SORT_ASC) $direction, int(SORT_REGULAR) $strategy) : Arrayy (Immutable)

Sort the current array by value.

$direction e.g.: [SORT_ASC, SORT_DESC, 'ASC', 'asc', 'DESC', 'desc']
$strategy e.g.: [SORT_REGULAR, SORT_NATURAL, ...]

a(3 => 'd', 2 => 'f', 0 => 'a')->sortValueNewIndex(SORT_ASC, SORT_NATURAL); // Arrayy[0 => 'a', 1 => 'd', 2 => 'f']
