/**
 * 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
