Custom arguments to add_filter

We can pass custom arguments to filters when using add_filter.

For example plugin needs to pass the order dynamically it can be done by using global variables.Sample code to change the order by using posts_orderby_request filter
.

global $corder;

$corder = 'asc';

add_filter( 'posts_orderby_request',function(){ 

                  global $corder; 

                  $val = " wp_posts.post_title $corder";
                  return $val;

                }

          );
