Without real information I can only wonder and guess.

Is TNS_ADMIN set to a directory or a file?  It should be a directory.
Try renaming sqlnet.ora temporarily or set the alias in tnsnames.ora
to something like "testdb.boo.com = (DESCRIPTION = ..."

Hello chris,

I've modified the variables in the apache user environment (in my case root at the moment) but that didn't amke any difference to php not being able to find tnsnames.ora. So the work around I've used is to use ORACLE_SID="desciption(...etc..... SID = )))"; ie the full description of the database alias within tnsnames.ora

However this is not good, so if you have any other idea please let me know. I'm flumuxed.
