Problem with classes, when extrasing key:

<?
 class klasa {
  function __construct($id_polaczenia_get=Null) {
   $this->config['local'] = Array ('key1' => 'value1',
    'key2'  => 'value2',
    'key3'  => 'value3');
  }
  function demo ($par=Null) {
   if ($par==Null) {
    $par = key ($this->config);  // should get 'local' key
  }

In this situation $par = Null instead of 'local'. After simple change:

  function demo ($par=Null) {
   if ($par==Null) {
    $___something = $this->config;
    $par = key ($this->config);
  }
it return properly key: 'local'.
