Does anyone know a hook, which doesn't depend on the template. A hook I can rely on in any situations?

there's some debug data collected while loading pages (i'm using 'all' hook to collect filter names) i would like to log to the screen. i need the data displayed, say, before

</body> 

tag.

Thanks.

Use the shutdown hook. It runs very late-- "just before PHP shuts down execution" per comments in the source.

Proof of concept:

add_action( 'shutdown', 
  function() {
    echo 'This runs very late in the page load';
  }
);
  • Oh, I was just thinking about it, actually. Hope it won't cause an infinite loop. Maybe it would be good to hook var_dump into it. – Alex Herrmann Oct 3 '13 at 21:31
  • It is almost always possible to cause an infinite loop. You just have to put your mind to it. :) But whether or not you do cause an infinite loop depends on the code you use in the callback. – s_ha_dum Oct 3 '13 at 21:33
  • Yep, at least if i use just var_dump, there's no infinite loop. Works great! Thank you! – Alex Herrmann Oct 3 '13 at 21:43
