[Phpgroupware-developers] Re: [OpenSync] a way to make a language wrapper

[Dave Hall]

Hi Armin,

This seems like a nice solution.  

One thing it doesn't seem to cope well with is php.  AFAIK it is not
possible to do something like this for php.

A possible solution - PHP (and phpgroupware) supports xmlrpc, so it
would be possible to communicate php based applications via xmlrpc.  The
solution you have outlined would allow developers to write the php
xmlrpc plugin layer in whatever language they were most comfortable
with.  You could of course go straight to db, but that would mean
duplicate all of the application's logic in another language, which
seems to me to be a waste of time.

Cheers

Dave
