PHP4 and Oracle Under NT

I have recently got through a tiring exercise in trying to get PHP 4 working with serving a remote Oracle 8i connection on and NT/Apache web server. I have used both the PHP 8 and 73 OCI libraries (both pre-compiled) but have found with both that it is not capable of making a remote connection for some reason. This is despite the fact that php 3 on the same system with the same oracle install is now working fine. The sqlnet.log file revealed that it was attempting a local connection every time - that is a bespoke BEQ protocol one. I managed to force it to make a remote connection via the registry (LOCAL = t:foo) in which case it failed to resolve TNS for the connection specified From what I can tell it doesn't seem to be picking up that I want a remote connection, or even my TNSNAMES.ORA file entries that identify the connection required. Its interesting that even when I specified tracing to be on in all the tnsnames files on the system it wasn't activated for these connections - is PHP 4 picking up its connection information from elsewhere? Has anyone experienced these problems? Thanks, Robin
