title: Trigger fake error 105
body: <p>I am trying to find a way to make my page look like it doesn't exist if a unique URL query not given. Can't find any solution. I've tried a PHP's trigger_error function, but it can't trigger </p>
  
  <blockquote>
    <p>ERR_NAME_NOT_RESOLVED.</p>
  </blockquote>
  
  <p>I could include not existing domain, but lol, it's not impossible. I am looking to do this in PHP, so I'm looking to know if that's possible at all. Or maybe someone can suggest a working solution?</p>
  
  <p>Thanks!</p>
