php module calling php code

Hi, can anyone point me to some examples/documentation for any of the following: C code calling methods of an object defined in a user's php code. (I know you can call user's php functions, but can this be done?) OR How would I define a PHP Object in C that could be used in the php script as if it was defined in the php script. thanks, colin -- Colin McDonald - colin@nexus.carleton.ca home: http://nexus.carleton.ca/~colin/ public key: http://nexus.carleton.ca/~colin/pubkey.asc fingerprint: http://nexus.carleton.ca/~colin/fingerprint.asc
