title: file_get_contents behind a proxy (using proxy list)
body: <p>I use this solution:</p>
  
  <pre><code>$aContext = array(
      'http' =&gt; array(
          'proxy' =&gt; 'tcp://192.168.0.2:3128',
          'request_fulluri' =&gt; true,
      ),
  );
  $cxContext = stream_context_create($aContext);
  
  $sFile = file_get_contents("http://www.google.com", False, $cxContext);
  
  echo $sFile;
  </code></pre>
  
  <p>How do I change the script so that instead of a proxy was used a proxy list in format:</p>
  
  <pre><code>...
  192.168.0.2:3128
  193.123.8.2:3128
  194.115.10.2:80
  195.178.0.2:80
  ...
  </code></pre>
