title: Read source code with PHP
body: <p>Is there away to read a source code from another site?
  Source code as HTML, when you right click on a site and then "Source code".</p>
  
  <p>I've tried:</p>
  
  <pre><code>&lt;? $f = fopen ("http://www.example.com/f", r);
  echo $f;
  ?&gt;
  </code></pre>
  
  <p>It did not work. How do I do this?</p>
