Ora 10g, PHP 4 and Apache 2

Up until recently, I was running Mandrake 9, Oracle 9i and whatever PHP 4 version was available at the time I installed my server (last time was around August of last year, IIRC). Didn't have any issues until someone compromised my server through an old SSH. I then decided to upgrade the whole lot to Fedora Core3, Oracle 10g, Apache 2 and PHP 4.3.10. I am able to make PHP scripts run on Apache2, but the connectivity to Oracle just isn't there. For an example, see: http://www.elnonio.dns04.com/test.php Now, the script may be a bit off since I was not using my oracle classes and was just writing straight OCI functions, but still this fails at the connection level. Has someone written a comprehensive how-to configure PHP 4 to access 10g databases? Any help appreciated to get my little site back up. Thanks, A. Contreras
