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.
