Multidimensional ArrayAccess

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

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

$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)

$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'

PhpDoc @property checking

The library offers a type checking for @property phpdoc-class-comments, as seen below:

/**
 * @property int        $id
 * @property int|string $firstName
 * @property string     $lastName
 * @property null|City  $city
 *
 * @extends  \Arrayy\Arrayy<array-key,mixed>
 */
class User extends \Arrayy\Arrayy
{
  protected $checkPropertyTypes = true;

  protected $checkPropertiesMismatchInConstructor = true;
}

/**
 * @property string|null $plz
 * @property string      $name
 * @property string[]    $infos
 *
 * @extends  \Arrayy\Arrayy<array-key,mixed>
 */
class City extends \Arrayy\Arrayy
{
    protected $checkPropertyTypes = true;

    protected $checkPropertiesMismatchInConstructor = true;
}

$cityMeta = City::meta();
$city = new City(
    [
        $cityMeta->plz   => null,
        $cityMeta->name  => 'Düsseldorf',
        $cityMeta->infos => ['lall'],
    ]
);

$userMeta = User::meta();
$user = new User(
    [
        $userMeta->id        => 1,
        $userMeta->firstName => 'Lars',
        $userMeta->lastName  => 'Moelleken',
        $userMeta->city      => $city,
    ]
);

var_dump($user['lastName']); // 'Moelleken'
var_dump($user[$userMeta->lastName]); // 'Moelleken'
var_dump($user->lastName); // Moelleken

var_dump($user['city.name']); // 'Düsseldorf'
var_dump($user[$userMeta->city][$cityMeta->name]); // 'Düsseldorf'
var_dump($user->city->name); // Düsseldorf

"checkPropertyTypes": activate the type checking for all defined @property in the class-phpdoc
"checkPropertiesMismatchInConstructor": activate the property mismatch check, so you can only add an array with all needed properties (or an empty array) into the constructor

OO and Chaining

The library also offers OO method chaining, as seen below:

simple example:

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

complex example:

/**
 * @property int    $id
 * @property string $firstName
 * @property string $lastName
 *
 * @extends  \Arrayy\Arrayy<array-key,mixed>
 */
class User extends \Arrayy\Arrayy
{
  protected $checkPropertyTypes = true;

  protected $checkPropertiesMismatchInConstructor = true;
}

/**
 * @template TKey of array-key
 * @extends  AbstractCollection<TKey,User>
 */
class UserCollection extends \Arrayy\Collection\AbstractCollection
{
    /**
     * The type (FQCN) associated with this collection.
     *
     * @return string
     */
    public function getType()
    {
        return User::class;
    }
}


$m = User::meta();

$data = static function () use ($m) {
    yield new User([$m->id => 40, $m->firstName => 'Foo', $m->lastName => 'Moelleken']);
    yield new User([$m->id => 30, $m->firstName => 'Sven', $m->lastName => 'Moelleken']);
    yield new User([$m->id => 20, $m->firstName => 'Lars', $m->lastName => 'Moelleken']);
    yield new User([$m->id => 10, $m->firstName => 'Lea', $m->lastName => 'Moelleken']);
};

$users = UserCollection::createFromGeneratorFunction($data);
$names = $users
    ->filter(static function (User $user): bool {
        return $user->id <= 30;
    })
    ->customSortValuesImmutable(static function (User $a, User $b): int {
        return $a->firstName <=> $b->firstName;
    })
    ->map(static function (User $user): string {
        return $user->firstName;
    })
    ->implode(';');

static::assertSame('Lars;Lea;Sven', $names);

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'

Collections

If you need to group objects together, it's not a good idea to use a simple array or Arrayy object. For these cases you can use the AbstractCollection class.

It will throw a InvalidArgumentException if you try to add a non valid object into the collection.

e.g.: "YOURCollection.php" (see example /tests/CollectionTest.php on github)

use Arrayy\Collection\AbstractCollection;

/**
 * @extends  AbstractCollection<array-key,YOURInterface>
 */
class YOURCollection extends AbstractCollection
{
    /**
     * The type (FQCN) associated with this collection.
     *
     * @return string
     */
    public function getType(): string
    {
        return YOURInterface::class;
    }
}

$YOURobject1 = new YOURClass();
$YOURobject2 = new YOURClass();

$YOURcollection = new YOURCollection($YOURobject1);
$YOURcollection->add($YOURobject2); // add one more object

// Or, you can use an array of objects.
//
// $YOURcollection = new YOURCollection([$YOURobject1, $YOURobject2]);

// Or, if you don't want to create new classes ... 
// ... and you don't need typehints and autocompletion via classes.
//
// $YOURcollection = \Arrayy\Collection::construct(YOURInterface::class, [$YOURobject1]);
// $YOURcollection->add($YOURobject2); // add one more object

// Or, if you don't like classes at all. ;-)
//
// $YOURcollection = \Arrayy\collection(YOURInterface::class, [$YOURobject1]);
// $YOURcollection->add($YOURobject2); // add one more object

foreach ($YOURcollection as $YOURobject) {
    if ($YOURobject instanceof YOURInterface) {
        // Do something with $YOURobject
    }
}

You can also use "dot-notation" to get data from your collections e.g.


## Pre-Defined Typified Collections

### simple example

This will throw a "TypeError"-Exception. 

```php
use Arrayy\Type\StringCollection;

$collection = new StringCollection(['A', 'B', 'C', 1]);

complex example

This will NOT throw a "TypeError"-Exception.

use Arrayy\Type\IntCollection;
use Arrayy\Type\StringCollection;
use Arrayy\Type\InstancesCollection;
use Arrayy\Type\TypeInterface;

$collection = InstancesCollection::construct(
    TypeInterface::class,
    [new StringCollection(['A', 'B', 'C']), new IntCollection([1])]
);

$collection->toArray(true); // [['A', 'B', 'C'], [1]]

Convert JSON-Data into Objects (Collection)


namespace Arrayy\tests\Collection;

use Arrayy\Collection\AbstractCollection;

/**
 * @extends  AbstractCollection<array-key,\Arrayy\tests\UserData>
 */
class UserDataCollection extends AbstractCollection
{
    /**
     * The type (FQCN) associated with this collection.
     *
     * @return string
     */
    public function getType()
    {
        return \Arrayy\tests\UserData::class;
    }
}

$json = '[{"id":1,"firstName":"Lars","lastName":"Moelleken","city":{"name":"Düsseldorf","plz":null,"infos":["lall"]}}, {"id":1,"firstName":"Sven","lastName":"Moelleken","city":{"name":"Köln","plz":null,"infos":["foo"]}}]';
$userDataCollection = UserDataCollection::createFromJsonMapper($json);

/** @var \Arrayy\tests\UserData[] $userDatas */
$userDataCollection->getAll();

$userData0 = $userDataCollection[0];
echo $userData0->firstName; // 'Lars'
$userData0->city; // CityData::class
echo $userData0->city->name; // 'Düsseldorf'

$userData1 = $userDataCollection[1];
echo $userData1->firstName; // 'Sven'
$userData1->city; // CityData::class
echo $userData1->city->name; // 'Köln'

float|int|string $value

Return:

bool

containsValues(array $needles): bool

↑ Check if all given needles are present in the array.

EXAMPLE: a([1, true])->containsValues(array(1, true)); // true

Parameters:

array<T> $needles

Return:

bool Returns true if all the given values exists in the array, false otherwise.

count(int $mode): int

↑ Counts all elements in an array, or something in an object.

EXAMPLE: a([-9, -8, -7, 1.32])->count(); // 4

For objects, if you have SPL installed, you can hook into count() by implementing interface {@see \Countable}. The interface has exactly one method, {@see \Countable::count()}, which returns the return value for the count() function. Please see the {@see \Array} section of the manual for a detailed explanation of how arrays are implemented and used in PHP.

Parameters:

int $mode [optional] If the optional mode parameter is set to COUNT_RECURSIVE (or 1), count will recursively count the array. This is particularly useful for counting all the elements of a multidimensional array. count does not detect infinite recursion.

Return:

int The number of elements in var, which is typically an array, since anything else will have one element. If var is not an array or an object with implemented Countable interface, 1 will be returned. There is one exception, if var is &null;, 0 will be returned. Caution: count may return 0 for a variable that isn't set, but it may also return 0 for a variable that has been initialized with an empty array. Use isset to test if a variable is set.

EXAMPLE: a([2 => 1, 3 => 2, 4 => 2])->uniqueNewIndex(); // Arrayy[1, 2]

Parameters: nothing

Return:

$this (Mutable)

unserialize(string $string): $this

↑ Unserialize an string and return the instance of the "Arrayy"-class.

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

Parameters:

string $string

Return:

$this

unshift(mixed $args): $this

↑ Prepends one or more values to the beginning of array at once.

Parameters:

array<TKey, T> ...$args

Return:

$this (Mutable) Return this Arrayy object, with prepended elements to the beginning of array.

validate(\Closure $closure): bool

↑ Tests whether the given closure return something valid for all elements of this array.

Parameters:

\Closure(T = default, TKey = default): bool $closure the predicate

Return:

bool TRUE, if the predicate yields TRUE for all elements, FALSE otherwise.

values(): static

↑ Get all values from a array.

EXAMPLE: $arrayy = a([1 => 'foo', 2 => 'foo2', 3 => 'bar']); $arrayyTmp->values(); // Arrayy[0 => 'foo', 1 => 'foo2', 2 => 'bar']

Parameters: nothing

Return:

static (Immutable)

walk(callable $callable, bool $recursive, mixed $userData): $this

↑ Apply the given function to every element in the array, discarding the results.

EXAMPLE: $callable = function (&$value, $key) { $value = $key; }; $arrayy = a([1, 2, 3]); $arrayy->walk($callable); // Arrayy[0, 1, 2]

Parameters:

callable $callable
bool $recursive [optional] Whether array will be walked recursively or no
mixed $userData [optional] If the optional $userData parameter is supplied, it will be passed as the third parameter to the $callable.

Return:

$this (Mutable) Return this Arrayy object, with modified elements.

where(string $keyOrPropertyOrMethod, mixed $value): static

↑ Returns a collection of matching items.

Parameters:

string $keyOrPropertyOrMethod The property or method to evaluate.
mixed $value The value to match.

Return:

static
