 * Hi
    Which wp function can I use to fetch the category number on a page? e.g. 
   if url being mydomainname/blog/cat=146, I want to retrieve 146
 * Of coarse, it can be done with a preg_match on the $_SERVER[‘REQUEST_URI’] but
   I like to use custom WP functions.
 * Goal: highlight the active class in the WP category list
    -  by using the current_category= argument.
 * thx

 * You can use the [get_query_var() function](http://codex.wordpress.org/Function_Reference/get_query_var)
   to do that.

 * Hi vtxyzzy,
 * thx for your reply.
    I looked and tried to retrieve the the id by $cat_Id = get_query_var(‘
   cat’); Nope… But did I make clear that I am on a page which displays all posts
   in a certain category? I am not on a post page. It looks like get_query_var is
   more suitable for that situation.
 * grtz I.

 * Try using this:
 *     ```
       $cat = $_GET['cat'];
       ```
