 * Hi.
    I want to test wordpress add rewrite rule function. I added below code to
   my theme’s functions.php in order to rewrite tha category permalinks.
 *     ```
       add_action( 'init', 'add_cat_rules' );
       function add_cat_rules() {
           add_rewrite_rule(
               "/cid=([0-9]+)/?",
               "index.php?cat=$matches[1]",
               "top");
       }
       ```
   
 * but it does not do anything.
    can anyone give me a working example on how to 
   rewrite my permalinks? Thanks a lot.
