WDDX (Web Distributed Data eXchange) is a programming-language-, platform-, and transport-neutral data interchange mechanism for passing data between different environments and different computers.

The adapter simply uses the wddx_*() PHP functions. Please read the PHP manual to determine how you may enable them in your PHP installation.

Additionally, the SimpleXML PHP extension is used to check if a returned NULL value from wddx_unserialize() is based on a serialized NULL or on invalid data.
