Yii Arrays

The package provides:

• ArrayHelper that has static methods to work with arrays;
• ArraySorter that has static methods for sort arrays;
• ArrayAccessTrait provides the implementation for \IteratorAggregate, \ArrayAccess and \Countable;
• ArrayableInterface and ArrayableTrait for use in classes who want to support customizable representation of their instances.

Requirements

• PHP 8.0 or higher.

Installation

composer require yiisoft/arrays

ArrayHelper usage

Array helper methods are static so usage is like the following:

$username = \Yiisoft\Arrays\ArrayHelper::getValue($_POST, 'username');

Testing against arrays

• isIn
• isSubset

Transformation

• index
• group
• filter
• map
• merge
• parametrizedMerge
• renameKey
• toArray

Other

• pathExists

ArraySorter usage

Array sorter has one static method which usage is like the following:

\Yiisoft\Arrays\ArraySorter::multisort($data, ['age', 'name'], [SORT_ASC, SORT_DESC]);

ArrayAccessTrait usage

ArrayAccessTrait provides the implementation for \IteratorAggregate, \ArrayAccess and \Countable.

Note that ArrayAccessTrait requires the class using it contain a property named data which should be an array. The data will be exposed by ArrayAccessTrait to support accessing the class object like an array.

Example of use:

use \Yiisoft\Arrays\ArrayAccessTrait;

class OfficeClassification implements \IteratorAggregate, \ArrayAccess, \Countable
{
    use ArrayAccessTrait;

    public array $data = [
        'a' => 'Class A',
        'b' => 'Class B',
        'c' => 'Class C',
    ];
}

$classification = new OfficeClassification();

echo 'Count classes: ' . $classification->count() . "\n"; // 3

$iterator = $classification->getIterator();
while ($iterator->valid()) {
    echo $iterator->current() . "\n"; // Class A, Class B, Class C
    $iterator->next();
}

ArrayableInterface and ArrayableTrait usage

ArrayableInterface and its implementation ArrayableTrait intended for use in classes who want to support customizable representation of their instances.

Example of use:

use \Yiisoft\Arrays\ArrayableTrait;
use \Yiisoft\Arrays\ArrayableInterface;

class Car implements ArrayableInterface
{
    use ArrayableTrait;

    public string $type = 'Crossover';
    public string $color = 'Red';
    public int $torque = 472;
}

$car = new Car();

$data = $car->toArray(['type', 'color']); // ['type' => 'Crossover', 'color' => 'Red']
