20.3. WDDX
The Web Distributed Data Exchange, or WDDX, is an XML language for describing data in a way that facilitates moving it from one programming environment to another. The intent is to relieve difficulty associated with sending data between applications that represent data differently. Traditionally this has been done by designing special interfaces for each case. For instance, you may decide that your PERL script will write out its three return data separated with tabs, using a regular expression to extract the text you later convert to integers. WDDX intends to unify the effort into a single interface. If you wish to learn more about WDDX, visit the home site at <http://www.openwddx.org/>.
Andrei Zmievski added WDDX support to PHP.
