// let's make sure the $_SERVER['DOCUMENT_ROOT'] variable is set
 if (!isset($_SERVER['DOCUMENT_ROOT'])) {
  if (isset($_SERVER['SCRIPT_FILENAME'])) {
   $_SERVER['DOCUMENT_ROOT'] = str_replace( '\\', '/', substr($_SERVER['SCRIPT_FILENAME'], 0, 0-strlen($_SERVER['PHP_SELF'])));
  };
 };
 if (!isset($_SERVER['DOCUMENT_ROOT'])) {
  if (isset($_SERVER['PATH_TRANSLATED'])) {
   $_SERVER['DOCUMENT_ROOT'] = str_replace( '\\', '/', substr(str_replace('\\\\', '\\', $_SERVER['PATH_TRANSLATED']), 0, 0-strlen($_SERVER['PHP_SELF'])));
  };
 };
 // $_SERVER['DOCUMENT_ROOT'] is now set - you can use it as usual...
