Converts an PHP Object to Array

toArray.md

Interface

interface Arrayable {
    public function toArray() : array;
}

Using a Trait:

trait JsonSerializableTrait {
    public function jsonSerialize()
    {
        // or array_filter(get_object_vars($this)); if you don't want to include null values
        return get_object_vars($this);
    }
}

Example:

class ClassToArray implements \JsonSerializable, Arrayable
{
    use JsonSerializableTrait;
    
    private $propOne = "one";
    private $propTwo = "two";
}

$toArrayTest = new ClassToArray();

assert($toArrayTest->jsonSerialize() == [ 'propOne' => 'one', 'propTwo' => 'two' ]);
