A short sample on how to attach a callback function to PHP class:

_events[$handler_name] = $method_name;
    }

    function execute(){
      $ename = 'event1';
      $intext = 'This comes from the inside';
      $outtext = '';
      if (isset($this->_events[$ename])){
        call_user_func($this->_events[$ename], &$outtext, $intext);
      }
      echo "test Class: $outtext\n";
    }
  }

  $test = new test();

  $test->attach('event1', 'outside');
  $test->execute();

?>

This script produces the following result:

Outside: This Comes from the inside
test Class: This comes from the outside
