 *     ```
       /*
       Plugin Name: TEST MYPERMALINK
       Plugin URI: http://www.pkphp.com/
       Description: Create every post to HTML cahe file, and refresh automatic.
       Version: 1.0
       Author: Askie
       Author URI: http://www.pkphp.com/
       */
   
       function Mypermalink($post_url,$post)
       {
       	if (false)
       	{
       		return "my permalink";
       	}
       	else
       	{
       		return get_permalink($post->ID);
       	}
       }
   
       add_filter('post_link',"Mypermalink",1,2);
       ```
