Description Author

This package can dump objects to strings in JSON and Array formats.

It provides interfaces that can be used to define classes of objects so they can output the values of their properties in JSON or serialized array format.

Classes that do not want to implement the toJSON and to toArray functions can use a trait that provides these functions.

Many applications have to use classes that need to save the values of their object variables to file, databases or other form of storage.

Usually they convert the values into string format like JSON or serialized arrays.

This package can add that functionality to any class by providing a trait that all classes can use to provide a built-in form of serialization to JSON or array formats.

Serializable Entity

Convert entity into array or json. Apply JsonSerializable into entity by extending a class.


Via composer:

composer require niko9911/niko9911/serializable-entity


You can use this to convert objects statically.

`EntityToArray::convert(object $entity ,[, int $recursionDepth = 2 [, bool $throwExceptionOnRecursionLimit = true ] [, bool $replaceValuesOnRecursionLimit = true ]]]): array`

Or if you want benefit from implementing \JsonSerializable interface you can extend class \Niko9911\Serializable\Serializable. In that case you will have 3 new methods in your class, toArray, toJson and jsonSerialize.

Example: Using Static Way


// These is just our example entities.
final class Flag
    / @var string */
    private $mainColor;
    / @var int */
    private $height;
    / @var int */
    private $width;
    / @var bool */
    private $registered;
    public function __construct(
        string $mainColor,
        int $height,
        int $width,
        bool $registered
        $this->mainColor = $mainColor;
        $this->height = $height;
        $this->width = $width;
        $this->registered = $registered;
    public  function getMainColor(): string
        return $this->mainColor;
    public  function getHeight(): int
        return $this->height;
    public  function getWidth(): int
        return $this->width;
    public  function getRegistered(): bool
        return $this->registered;

// It is not mandatory to extend. Only if you want benefit from
// implementing \JsonSerializable and having toArray, toJson methods.
final class Country extends \Niko9911\Serializable\Serializable
    // If you don't want implement \JsonSerializable,
    // but you want methods `toArray & toJson` into
    // you entity, you can add this trait.
    use \Niko9911\Serializable\SerializableTrait;
    / @var string  */
    private $name;
    / @var int  */
    private $id;
    / @var Flag */
    private $flag;
    public function __construct(string $name, int $id, Flag $flag) 
        $this->name = $name;
        $this->id = $id;
        $this->flag = $flag;
    public function getName(): string
        return $this->name;
    public function getId(): int
        return $this->id;
    public function getFlag(): Flag
        return $this->flag;

$entity = new Country('Finland', 358, new Flag('Blue', 150, 245, true));

$result1 = \Niko9911\Serializable\EntityToArray::convert($entity);
$result2 = $entity->toArray();
$result3 = $entity->toJson();
$result4 = \json_encode($entity);

var_dump($result1); // ['name'=>self::NAME,'id'=>self::CODE,'flag'=>['mainColor'=>self::MAIN,'height'=>self::SIZE[0],'width'=>self::SIZE[1],'registered'=>self::REGI,'options'=>[]]]
var_dump($result1 === $result2); // True

var_dump($result3); // {"name":"Finland","id":358,"flag":{"options":[],"mainColor":"Blue","height":150,"width":245,"registered":true}}
var_dump($result3 === $result4); // True
