arrr ✅
======

[](#arrr-)

Array class for PHP

Installation
------------

[](#installation)

```
$ composer require pisc/arrr
```

Instantiation:
--------------

[](#instantiation)

```
// shorthand function (global function)
$array = ar([ 'someKey' => 'someValue' ]);

// constructor
$array = new Arrr([ 'someKey' => 'someValue' ]);

$array = new Ar([ 'someKey' => 'someValue' ]); // returns Ar instance
$array->mapIt(function($item) {
	return $item . "_suffix";
}); // returns Arrr instance

// factory
$array = Arrr::ar([ 'someKey' => 'someValue' ]);
$array = Arrr::instance([ 'someKey' => 'someValue' ]);
$array = Ar::ar([ 'someKey' => 'someValue' ]);
$array = Ar::instance([ 'someKey' => 'someValue' ]);
```

How to use:
-----------

[](#how-to-use)

```
use pisc\arrr\arrr;

$array = ar([ 'someKey' => 'someValue' ]);
```

```
$flat = Ar::flatten([ 'cow', [ 'bear', ['bunny', 'santa' ], 'rabbit' ]]);
```

Most methods are callable as:

- Static method with the first parameter the array - Ar::map($array, function($item) { return $item; })
- Instance method which returns a new instance of Arrr - $Arrr->map(function($item) { return $item; })
- Instance method which works on the current instance - $Arrr->mapIt(function($item) { return $item; })

Convention
----------

[](#convention)

All methods ending on 'It' modify the array itself and return itself, so you can do something like:

```
$places = ar([
	'Amsterdam',
	'Berlin',
	'Paris',
	'Vienna',
	'Rome',
	'Madrid'
]);

$places->filterIt(function($place) {
	return in_array($place[0], [ 'A', 'V', 'R' ]);
});

$places->mapIt(function($place) {
	return "To destination {$place}";
})

echo $places->toJson();

// returns
'[ "To destination Amsterdam", "To destination Vienna", "To destination Rome" ]'
```

Run tests
---------

[](#run-tests)

```
# When installed globally
$ phpunit

# When installed locally
$ ./vendor/bin/phpunit
```

Methods
-------

[](#methods)

### sortBy (sortByIt)

[](#sortby-sortbyit)

Sort an array by multiple keys or result of a closure When a compare function result in 0, it will test the next key or closure

accepts:

- $sortByKeys ((array) string / closure )
- $methods ((array) string / callable )

```
$array = ar([
	(object)[ 'id' => 1, 'name' => 'Jack', 'length' => 180 ],
	(object)[ 'id' => 2, 'name' => 'Jack', 'length' => 150 ],
	(object)[ 'id' => 3, 'name' => 'Ben', 'length' => 180 ],
	(object)[ 'id' => 4, 'name' => 'Ben', 'length' => 150 ],
	(object)[ 'id' => 5, 'name' => 'Vince', 'length' => 180 ],
	(object)[ 'id' => 6, 'name' => 'Vince', 'length' => 150 ],
]);

$sortedArray = $array->sortBy([ 'length', 'name' ], [ 'Sort::byDefault', 'strcmp' ]);

// result
[
	(object)[ 'id' => 4, 'name' => 'Ben', 'length' => 150 ],
	(object)[ 'id' => 2, 'name' => 'Jack', 'length' => 150 ],
	(object)[ 'id' => 6, 'name' => 'Vince', 'length' => 150 ],
	(object)[ 'id' => 3, 'name' => 'Ben', 'length' => 180 ],
	(object)[ 'id' => 1, 'name' => 'Jack', 'length' => 180 ],
	(object)[ 'id' => 5, 'name' => 'Vince', 'length' => 180 ],

]
```
