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.
