Oracle 10g Instant Client (free download available) is
the easiest way for PHP to connect to a remote Oracle database, requiring
installation of only three libraries.
The Instant Client libraries used by PHP
access Oracle’s current API, called OCI8. (This C interface takes its
name from being first introduced in Oracle8.)
PHP Oracle 8
Functions can call Oracle 8.1.7, 9.x, or 10.x directly, or optional
abstraction classes like PEAR MDB2 and ADOdb can be used for
convenience.
