@noinspection PhpIncludeInspection - Have to use this twice??

Is this correct?

if(file_exists(_DOCROOT.'/library/classes/'.$sClassName.'.php'))
  /** @noinspection PhpIncludeInspection */
  require_once
   /** @noinspection PhpIncludeInspection */
   _DOCROOT."/library/classes/$sClassName.php";

If I only use it once, like this, I still get an warning:

if(file_exists(_DOCROOT.'/library/classes/'.$sClassName.'.php'))
  /** @noinspection PhpIncludeInspection */
  require_once _DOCROOT."/library/classes/$sClassName.php";
