/**
* Object PHP_Serializer
* JavaScript to PHP serialize / unserialize class.
* This class is designed to convert php variables to javascript
* and javascript variables to php with a php serialize unserialize
* compatible way.
*
* PARSABLE PHP TO JAVASCRIPT VARIABLES:
* [ PHP TYPE ] [ JAVASCRIPT TYPE ]
* array Array
* class Object (*)
* string String
* boolean Boolean
* undefined or null null
* integer / double Number
*
* PARSABLE JAVASCRIPT TO 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 anything (*)
* __class anything (*)
*
* (*) 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.
* However is possible to change public parameters.
* Lambda, Resources or other dedicated PHP variables are not usefull for JavaScript.
* (i.e.
* $v = create_function('', 'return 1;'); serialize($v);
* $conn = mydb_connect(); serialize($conn);
* )
* There are same restrictions for javascript functions too then these will not be sent
* (but will be filtered / ignored automatically).
* _____________________________________________
*
* EXAMPLE:
* var php = new PHP_Serializer();
* alert(php.unserialize(php.serialize(somevar)));
* // should alert the original value of somevar

* @credits Special thanks to Fabio Sutto for some ideas and some debug
* Special thanks to kentaromiura for a faster loop idea while unserialize
* @version 1.6, tested on FireFox 1.0.7, FireFox 1.5, IE 6 SP2 and Opera 8
