Alison Holloway has a new note on her blog today about the release of the latest version of the Zend Core for Oracle - version 2.0.
Zend have just released a new version of Zend Core for Oracle. This is a prebuilt and tested stack of Apache, PHP and Oracle Instant Client. If you haven't used it before, you will like the easy setup. I promise. [...] Zend Core for Oracle release 2.0 includes PHP 5.2.1, the refactored OCI8 driver, Oracle Instant Client, and an optional Apache HTTP Server 2.2.2.
This new version is supported on OSes like Oracle Enterprise Linux, X86 running Windows XP/2003/Vista and Sun Solaris Sparc 8, 9 10 just to name a few. She also mentions the Underground PHP and Oracle Manual [pdf] as a reference to help you get things running if you're stuck.
