Re: Oracle/PHP Issue

The problem is in the 9.2 client and oracle module. You are using Oracle7 OCI calls (oracle 6, really)
which are not very reliable with Oracle9. You have to use oci_connect and oci_close instead of the ancient
"ORA_*" functions. Besides, "ORA_*" functions (--with-oracle config directive) will not be supported in the
next major release of PHP (PHP 5), only OCI8 will be supported. You should rebuild your PHP --without-oracle Unfortunately, despite the eerie similarity to perl, PHP doesn't have anything like DBI which would make
database access uniform across the database world. May I abuse this opportunity and ask you which IDE are
you using with PHP? I'm using Bluefish, but the fish is rotten. If you answer with "vi", the three of us
(Smith, Wesson & me) will be very, very angry.

The goal is to make a connection to this instance from the web server, which is running Red Hat Enterprise Server 3.0 and using the Oracle 9.2.0.4 client. It is using Apache 2.0.46 and PHP 4.3.2 (oracle, oci8, curl, and dom modules).
