Web Tool Bag

To expand on the nice bit of code Mike Willbanks wrote and Alexander tidied up, I turned the whole thing in a function that removes all the globals added by register_globals so it can be implemented in an included functions.php and doesn't litter the main pages too much.

<?php
//Undo register_globals
function unregister_globals() {
    if (ini_get(register_globals)) {
      $array = array('_REQUEST', '_SESSION', '_SERVER', '_ENV', '_FILES');
      foreach ($array as $value) {
      foreach ($GLOBALS[$value] as $key => $var) {
      if ($var === $GLOBALS[$key]) {
      unset($GLOBALS[$key]);
      }
      }
      }
    }
}
?>
