High performance PHP applications with Oracle Database
The PHP OCI8 2.0 extension for Oracle Database is now "production" status. The source code is included in the latest PHP versions and is also available on PECL to update your OCI8 extension in PHP 5.2 and later versions. The extension compiles with Oracle 10.2 or later client libraries. Oracle's standard cross-version database connectivity applies, allowing PHP to connection to multiple versions of Oracle Database.
PHP OCI8 is part of the PHP open source project. It is maintained by Oracle, and is under active development.
