title: PHP Force Apache error
body: <p>Thanks to this forum, I learnt PHP header function does not actually send header to Apache server but only to the client.</p>
  
  <p>What I wanna do is to generate an error 500, and let Apache displays its corresponding page. Is there a way to force it ?</p>
  
  <p>Thanks in advance !
  (and allez les bleus !)</p>
