This extension adds support for Oracle database server access. See also the OCI8 extension.
Note: This extension has been moved to the PECL repository and is no longer bundled with PHP as of PHP 5.1.0.
You have to compile PHP with the option --with-oracle[=DIR], where DIR defaults to your environment variable ORACLE_HOME.
The constants below are defined by this extension, and will only be available when the extension has either been compiled into PHP or dynamically loaded at runtime.
