Here is the latest ( DEC 2007 ) srpm for the subj for CentOS/REL 5.
it does NOT have an instant client support. if you need that go to
Oracle OSS project or ask in forums on OTN.
To make a binary you have to set up in your env ORACLE_HOME and LD_LIBRARY_PATH and make sure that there are no other php* packages installed in the system.
Thank you.
