PHP 5.3.8 RPMs are on oss.oracle.com
By cj on Aug 30, 2011
I've built PHP 5.3.8 RPM packages with various common extensions (and the latest OCI8 1.4.6) for Linux x64. They are downloadable at oss.oracle.com/projects/php/. These binaries might be useful for quick testing. They are unsupported.
Oracle customers with support using Oracle Linux 5.6+ may prefer the stable PHP 5.3.3 php53-* packages available on ULN. The OCI8 extension is also available there.
