title: Reading mp4 files with PHP
body: <p>I'm trying to read mp4 file with PHP and what I'm doing now is this:</p>
  
  <pre><code>&lt;?php
  header("Content-Length: filesize");
  readfile('file.mp4');
  ?&gt;
  </code></pre>
  
  <p>but this way I can't skip or even go back until the video is not loaded 100%. Of course when I  read directly from the file (video.mp4) everything goes well.</p>
  
  <p>Thanks.</p>
