If the Oracle Database is on the same machine as PHP, the database software already contains the necessary libraries. When PHP is on a different machine, use the free Oracle Instant Client libraries. For details refer to the OCI8 Requirements section.

Use `--with-pdo-oci[=DIR]` to install the PDO Oracle OCI extension, where the optional `[=DIR]` is the Oracle Home directory. `[=DIR]` defaults to the `$ORACLE_HOME` environment variable.

Use `--with-pdo-oci=instantclient,prefix,version` for an Oracle Instant Client SDK, where prefix and version are configured.

    // Using $ORACLE_HOME
    $ ./configure --with-pdo-oci

    // Using OIC for Linux with 10.2.0.3 RPMs with a /usr prefix
    $ ./configure --with-pdo-oci=instantclient,/usr,10.2.0.3
