WDDX is kind of dicey, it doesn't handle a lot of the data types correctly. About a year an a half ago, I tried to use it as a serializer and it really confused the datatypes in PHP. If you are doing something simple, it will probably work, but I wouldn't count on it. I have an extension to PHP that could work for you. Take a look at XMLDBX at http://www.mohawksoft.org. You'll need to get it from CVS. Put it in the "ext" directory and run ./buildconf.sh --force, then configure with --with-xmldbx It started out as a fix to wddx, but essentially became a rewrite. I've been using it on a few sites for over a year now. -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php
