Thanks to Mikael Johannsson for his PECL project on WBXML. He has just released a new PECL package that does all the encryption and decryption for us. That takes such a load of this project because that is a very hard nut to crack. I am not saying we are stopping from making a class object that does this all in PHP but we can set it down the ladder a bit and focus more SyncML standardization and sync logic.
PHP Architect has published an article I wrote about creating a PHP SyncML application. I hope this gets more involved with development of this API. I have gotten lots of emails asking for a finished product but no one wants to help. I am just as excited as everyone else to get it done but I need help.
I have uploaded source code today to get everything started. It is a working SyncML program that only works on uncompressed transactions. WBXML is the next hurdle, then the back side integration. There is still alot to do. If you want to help let us know.
