Сериализация объектов через куки - Разработка расширений для Joomla

$serial = serialize( $object ); // serializing existent object( class instance )
$index = 'element'; // element name for $_COOKIE array
setcookie( $index, $serial, ...cookie_parameters.. ); // sets cookie

/**
 * <--
 * next you MUST include file with CLASS DECLARATION for $object
 * <--
 */
include( 'filename_with_class' ); //

$index = 'element'; // element name for $_COOKIE array
$serib = $_COOKIE[$index]; // getting data from cookie
$serib = urldecode( $serib ); // reverse url decoding of string
if( get_magic_quotes_gpc() ) $serib = stripslashes( $serib ); // if MAGIC QUOTES is ON, then we need to strip slashes
$object = unserialize( $serib ); // back unserialize the string
