/**
* Object PHP_Serializer
* JavaScript to PHP serialize / unserialize class.
* This class converts php variables to javascript and vice versa.
*
* PARSABLE JAVASCRIPT < === > PHP VARIABLES:
* [ JAVASCRIPT TYPE ] [ PHP TYPE ]
* Array < === > array
* Object < === > class (*)
* String < === > string
* Boolean < === > boolean
* null < === > null
* Number < === > int or double
* Date < === > class
* Error < === > class
* Function < === > class (*)
*
* (*) NOTE:
* Any PHP serialized class requires the native PHP class to be used, then it's not a
* PHP => JavaScript converter, it's just a usefull serilizer class for each
* compatible JS and PHP variable types.
* Lambda, Resources or other dedicated PHP variables are not usefull for JavaScript.
* There are same restrictions for javascript functions*** too then these will not be sent.
*
* *** function test(); alert(php.serialize(test)); will be empty string but
* *** mytest = new test(); will be sent as test class to php
* _____________________________________________
*
* EXAMPLE:
* var php = new PHP_Serializer(); // use new PHP_Serializer(true); to enable UTF8 compatibility
* alert(php.unserialize(php.serialize(somevar)));
* // should alert the original value of somevar

* @date 2005/11/26
* @lastmod 2006/05/15 19:00 [modified stringBytes method and removed replace for UTF8 and \r\n]
* [add UTF8 var again, PHP strings if are not encoded with utf8_encode aren't compatible with this object]
* [Partially rewrote for a better stability and compatibility with Safari or KDE based browsers]
* [UTF-8 now has a native support, strings are converted automatically with ISO or UTF-8 charset]
*
* @specialthanks Fabio Sutto, Kentaromiura, Kroc Camen, Cecile Maigrot, John C.Scott, Matteo Galli
*
* @version 2.2, tested on FF 1.0, 1.5, IE 5, 5.5, 6, 7 beta 2, Opera 8.5, Konqueror 3.5, Safari 2.0.3
