This extension adds support for Oracle database server access.
See also the OCI8 extension.
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.
