title: Can't launch vlc from apache using php
body: <p>I have a problem when I want to launch VLC from Apache using PHP. I'm using Ubuntu 10.10 (It works with Archlinux).</p>
  
  <pre>
  Apache/2.2.16 (Ubuntu) Server
  PHP 5.3.3-1ubuntu9.3 with Suhosin-Patch
  </pre>
  
  <p>I launched Apache with my own user.</p>
  
  <p>Code:</p>
  
  <pre><code>&lt;?php
  $foo = system('/usr/bin/cvlc');
  echo $foo;
  ?&gt;
  </code></pre>
  
  <p><code>$foo</code> is empty.<br>
  when I launch VLC from command line it works.<br>
  Simple <code>touch foo</code> works.</p>
  
  <p>Can you help me? Thanks.</p>
