title: PHP SFTP with proxy
body: <p>I'm searching for a class / extension / whatever that allows me to use a proxy for an SFTP connection in PHP.</p>
  
  <p>I've checked the <a href="http://php.net/manual/en/function.ssh2-sftp.php" rel="nofollow">ssh2_ftp</a> function and <a href="http://phpseclib.sourceforge.net/" rel="nofollow">phpseclib</a>, but I didn't find any reference to proxy settings...</p>
  
  <p>Any idea?</p>
