I get a similar problem, mine is just in English 😉
Using PHP 4.0.3 I cannot seem to connect to a remote Oracle dB using the OCI 7 calls e.g.
The connect string
$conn = Ora_Logon("scott", "tiger");
connects fine to the local dB on the NT web server, but I get the error
Warning: Oracle: Connection Failed: ORA-12154: TNS:could not resolve service name in E:\apache\htdocs\php3\oraremote.php3 on line 18
when I use a connect string such as
$conn = Ora_Logon("scott@somedb","tiger");
I get a similar error when I try and connect to an Oracle dB via ODBC.
All these work 100% using PHP 3.0.16, and with PHP 4.0.3 the ODBC connections to Access and MS SQL server and the OCI8 stuff works fine.
It seems asif it can't get hold of the "tnsnames.ora" file, as suggested by Sylvain.
