 * for the life of me i can not hook into this supposedly available action.
 * <?php
 * add_action( ‘permalink_structure_changed’, ‘my_custom_function’ );
 *  function my_custom_function()
    { echo ‘<script>alert();</script>’; }
 * ?>

 * Make sure your not leaving the `<?php` and the close in there. There’s already
   one in your functions file. But that’s not even how you change the structure.

 * Verifying a hook fires by setting an alert box is unreliable in PHP because the
   browser is not always expecting output when actions fire. In such cases the output
   is ignored. Try using error_log() to send debug messages to the log file.

   my other php anywhere. sorry for confusion.
