Trying to figure out correct syntax

[Blackhat]

I cant get this to work. Im using this in a plugin

PHP Code:

// The MAX_PATH below should point to the base of your OpenX installation
  define('MAX_PATH', '/*****/*****/*****/html/ads');
  if (@include_once(MAX_PATH . '/www/delivery/alocal.php')) {
    if (!isset($phpAds_context)) {
      $phpAds_context = array();
    }
    $phpAds_raw = view_local('', 12, 0, 0, '', '', '0', $phpAds_context);

  } 


and try to call it as posted above, but it only prints the [html] part as text
