# The Serializable interface

## Wstęp

Interface for customized serializing.

Classes that implement this interface no longer support __sleep() and __wakeup(). The method serialize is called whenever an instance needs to be serialized. This does not invoke __destruct() or has any other side effect unless programmed inside the method. When the data is unserialized the class is known and the appropriate unserialize() method is called as a constructor instead of calling __construct(). If you need to execute the standard constructor you may do so in the method.

## Zestawienie interfejsu

Serializable
Serializable {
/* Metody */
abstract public string serialize ( void )
abstract public mixed unserialize ( string `$serialized` )
}

Przykład #1 Basic usage

`<?php
class obj implements Serializable {
private $data;
public function __construct() {
$this->data = "My private data";
}
public function serialize() {
return serialize($this->data);
}
public function unserialize($data) {
$this->data = unserialize($data);
}
public function getData() {
return $this->data;
}
}
$obj = new obj;
$ser = serialize($obj);
$newobj = unserialize($ser);
var_dump($newobj->getData());
?>`
