php SMPP

Hi all, Just wondering if anybody has had experience using SMPP with php. I have used the one available class that has limited functionality for sending simple messages, but would like to do a little bit more (concatenated messages over 170 chars.). Ipworks has some libraries, but I have not been able to compile the php side of them (keep getting compilation errors for on file), so now I am stuck. Any pointers to existing scripts, or advice on how to create SMPP pdu's manually will be very appreciated. thanks Kyriacos -- Kyriacos Sakkas Netsmart Development Team Tel: + 357 22 452565 Fax: + 357 22 452566 kyriacos(at)netsmart.com.cy http://www.netsmart.com.cy Taking Business to a New Level!
