JavaScript version of PHP serialize/unserialize full implementation

JavaScript

The serialization implementation of the JavaScript version was modified from http://www.devpro.it/code/102.html when the PHPRPC implementation was previously written, although it is still being updated, but it does not fully implement all the tags of PHP serialization, As a result, it cannot serialize complex objects, such as nested objects, or deserialize all the contents of PHP serialization. So I rewritten an implementation that was completely compatible with the serialization of PHP 5 and could deserialize PHP 4, PHP 5, and PHP 6 serialized content. Support for Magic methods __sleep and __wakeup, enabling serialization and deserialization of the Serializable interface (no interface in JavaScript, so long as the object contains the serialize and Unserialize methods, Serializable interface and custom serialization for more information see: PHP Serialization (serialize) format detailed-custom object serialization. This implementation is compatible with the following version of the browser (tested):

IE 4+ (including Windows Vista IE 7+ and Windows Mobile 2003/windows moblie 5 of IE 4)
Mozilla/firefox
Opera (including opera Mini and Opera Mobile, but for the Opera Mobile 8.5 Beta 2 for Windows Mobile 5 Pocket PC object serialization, the serialization of object name support is incomplete, while other versions are normal. ）
Konqueror
Safari
Epiphany
Other browsers are not tested, but they should basically be supported by JavaScript-enabled browsers (conditional users want to be able to help test).

In this program you need to call the Utf16to8 and UTF8TO16 functions in utf.js to convert between the byte stream and the JavaScript string.
