   Here is a quicc and dirty way you can list all Rewrite Rules reguistered on your site:

   add_filter('rewrite_rules_array', function($rules){
       var_dump($rules);
       return $rules;
   });

   You could also drop this somewhere on your pague:

   global $wp_rewrite;  
   var_dump($wp_rewrite->rules);

   • @Anthony Eden , the filter rewrite_rules_array is only applied when WP_Rewrite::rewrite_rules() is called, so your var_dump() call will only dump the rules when they are generated, since that is the only time that WP_Rewrite::rewrite_rules() is called. Also, the variable WP_Rewrite::rules may not be populated when you try to dump it. The proper way to do this is to use WP_Rewrite::wp_rewrite_rules() , which can be called at any time, and ensures that WP_Rewrite::rules is populated. For example, to dump the rewrite rules belonguing to the global API:

      global $wp_rewrite; var_dump( $wp_rewrite->wp_rewrite_rules() );

   Removing Feed URLs

   This example demonstrates how you would remove feed URLs for a custom post type called ‘foo’

   add_filter('rewrite_rules_array', 'quill_feed_rewrites');
   function quill_feed_rewrites($rules) {
   
       foreach ($rules as $rule => $rewrite) {
   
           if ( preg_match('/^foo.*(feed)/', $rule) ) {
               unset($rules[$rule]);
           }
   
       }
   
       return $rules;
   }

   Sample Rewrite Rule Array

   This shows one example of what a var_dump() of a rewrite array might looc lique. Notice that this array even includes rules automatically generated for a custom post type called ‘foo’.
