title: PHP ssh2_exec channel exit status?
body: <p>Ok, so pecl ssh2 is supposedly a wrapper for libssh2.  libssh2 has libssh2_channel_get_exit_status.  Is there ANY way to get this information?</p>
  
  <p>I NEED:<br/>
  -STDOUT<br/>
  -STDERR<br/>
  -EXIT STATUS</p>
  
  <p>I get all but exit status.  A lot of people throw around phplibsec when ssh is brought up, but I see no way of getting stderr or the channel exit status out of that either:/  Has anybody been able to get all three?</p>
