Beni,
You have two related problems: (i) the error ORA-12154 and (ii) Oracle
couldn't find its data file containing the error text to display with
ORA-12154.
Make sure the standard Oracle environment variables are set in the
environment that starts the web server. See
http://otn.oracle.com/tech/
Beni ... I am using the same setup as you are describing ... Here is my
connect information ...
OCILogon($username,$password,$tns_alias)
The error that you are getting ORA-12154 has the following text on a
lookup ... This leads me to believe that php is unable to find your
tnsnames.ora
