title: PHP system function strange behavior
body: <p>I have a strange behavior with PHP system function. In this php script there are only 2 instructions (the rest being pure html):</p>
  
  <pre><code>&lt;?php echo system('cgi-bin/gallery2/galleryheaderview.cgi'); ?&gt;
  &lt;?php echo system('cgi-bin/gallery2/galleryview.cgi'); ?&gt;
  </code></pre>
  
  <p>The first cgi just returns a single line as you can check here
  <a href="http://reboltutorial.com/cgi-bin/gallery2/galleryheaderview.cgi" rel="nofollow noreferrer">http://reboltutorial.com/cgi-bin/gallery2/galleryheaderview.cgi</a></p>
  
  <p>It returns </p>
  
  <blockquote>
    <p>My Gallery</p>
  </blockquote>
  
  <p>But the whole php script returns My Gallery Twice:</p>
  
  <blockquote>
    <p>My Gallery
    My Gallery</p>
  </blockquote>
  
  <p><a href="http://reboltutorial.com/gallery2.php" rel="nofollow noreferrer">http://reboltutorial.com/gallery2.php</a></p>
  
  <p>Is there a reason (I don't use My Gallery in second cgi script of course see <a href="http://reboltutorial.com/cgi-bin/gallery2/galleryview.cgi" rel="nofollow noreferrer">http://reboltutorial.com/cgi-bin/gallery2/galleryview.cgi</a>) and how to prevent this ?</p>
  
  <p>Thanks.</p>
