Versuche, alle Variablen im Skript automatisch zu deaktivieren.

Habe es so versucht:

  echo '<br /> Variables in Script before unset(): <br />';
  print_r(array_keys(get_defined_vars()));
  echo '<br /><br />';
  var_dump(get_defined_vars());

  // Creates string of comma-separated variables(*) for unset.
  $all_vars = implode(', 
 Warum funktioniert es nicht?
 Gibt es einen besseren Weg, dies zu tun?
Danke fürs Helfen
(*) It's seems somewhat that it does not really create the variables, but a string that looks like variables...
, array_keys(get_defined_vars()));

  echo '<br /><br />';
  echo '<br />List Variables in Script: <br />';
  echo $all_vars;
  unset($all_vars);

  echo '<br /><br />';
  echo '<br />Variables in Script after unset(): <br />';
  print_r(array_keys(get_defined_vars()));
  echo '<br />';
  var_dump(get_defined_vars());
