Chris Jones has a quick note concerning the update in version of the PHP packages for their Oracle Enterprise Linux distribution:
I've updated the PHP RPMs on http://oss.oracle.com/projects/php/ and released PHP 5.2.8 RPMs with the OCI8 extension for Oracle Enterprise Linux (i.e Red Hat Enterprise Linux) 4.7 and 5.2 on 32 and 64 bit platforms.
The packages were built for Oracle Enterprise Linux 4.7 on the x86 platform (but will also install on a Red Hat Enterprise Linux server). The three major components - command line, CGI interface and Apache module - are all included as well as several standard PHP extensions. The install will require that you have the Oracle Instant Client installed.
