How to manage SYBASE error messages and return code with PHP4

Hi, My name is Bertrand AUDRAS and I am working in France around SYBASE dataserver, PHP4 and Apache- I am very interrested by PHP capabilities with Sybase Adaptive Server Enterprise (ASE) on Linux RedHat but I cannot found the way to manage ASE messages and errors in PHP4- I would like to manage: - the return code on a query (like the Sybase global variable @@error or CTLIB ct_send/ct_results return codes) - the differents messages sent by the dataserver to clients (like CTLIB messages CS_MESSAGE_CB, CS_CLIENTMSG_CB, CS_SERVERMSG_CB) I have heard that Zeev Suraski is the developper of the SYBASE driver and I will really appreciate to be contacted back on this subject- Thanks in advance, regards Bertrand ________________________________________________________________________ Get Your Private, Free E-mail from MSN Hotmail at http://www.hotmail.com
