Details

Nearly at the end of OutputPage::output() but before OutputPage::sendCacheControl() and final ob_end_flush() which will send the buffered output to the client. This allows for last-minute modification of the output within the buffer by using ob_get_clean().

• $output: The OutputPage object where output() was called

How to use

$wgHooks['AfterFinalPageOutput'][] = "fnAfterAll";
function fnAfterAll($output) {
  $out = ob_get_clean();
  // change final html in $out
  ob_start();
  echo $out;
  return true;
}
