/** * 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 * --------------------------------------------- * @author Andrea Giammarchi * @site www.devpro.it * @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 */ function PHP_Serializer(UTF8){function serialize(v){var s;switch(v){case
