title: Php Shell Exec doesnt work
body: <p>i've got a site on my raspberry pi with remote launching music. </p>
  
  <p>The script in .php looks like this:</p>
  
  <pre><code>&lt;?php $message=shell_exec("cvlc /home/pi/1373_128.m3u &amp;");
  header('Location:index.html'); ?&gt;
  </code></pre>
  
  <p>It is working from a command line ( php5 radioon.php )</p>
  
  <p>But when I am trying to launch it from website it is not, any ideas what may be wrong? The php script itself is fine, it is working when it comes to turn on light in room etc.</p>
