This extension is DEPRECATED and UNBUNDLED as of PHP 7.4.0.
These functions are intended for work with » WDDX.
Do not pass untrusted user input to wddx_deserialize. Unserialization can result in code being loaded and executed due to object instantiation and autoloading, and a malicious user may be able to exploit this. Use a safe, standard data interchange format such as JSON (via json_decode and json_encode) if you need to pass serialized data to the user.
