title: PHP 5.5 short_open_tag=on Security Hole?
body: <p>I've upgraded to PHP5.5 and in the <strong>PHP.ini</strong> now <code>short_open_tag=off</code> and I recognized this because some files are now not running because <code>&lt;?</code> instead of <code>&lt;?php</code>.</p>
  
  <p>Now there are two solutions scouting for any php file and change the open tag to <code>&lt;?php</code> or activate <code>short_open_tag=on</code></p>
  
  <p>Is there any security problem with the second option?</p>
