 * routing in a specific front controller that shares a common CI installation.
 *
 * IMPORTANT:  If you set the routing here, NO OTHER controller will be
 * callable. In essence, this preference limits your application to ONE
 * specific controller.  Leave the function name blank if you need
 * to call functions dynamically via the URI.

 * items or override any default config values found in the config.php file.
 * This can be handy as it permits you to share one application between

是不是没有php解析器？
