Comment 7 for bug 1022688

Yes but in :

if (!$errno) means if (not false) or if not 0 (0 meaning false) and not(0) meaning true this if condition must be true

 if (!$errno) { /***** this must be true******/) so the errno must be equal to 0 to have a 1 (true) in this case a
                     not(0) will make this condition true or (1)
     $returnvalues = json_decode($returnjsonstring, true);
     if ($returnvalues['result'] == 1) { (/******** this must be true *******/)
        if ($returnvalues['values']['auth'] == 1) (/*******this must be false********/)
           if (isset($returnvalues['values']['redirect']))
              // redirect to url $returnvalues['values']['redirect']
           else
             echo "Login successful but no connection token created. Is this intentional?";
        else
           /****** cause these are the only ways to have a successful login ******/
           echo "Login unsuccessful";
     } else {
        The first if condition return a false and
        echo "Some exception occurred using the web service: " . $returnvalues['values']['type'] . " " . $returnvalues['values']['message'];
     }
  }
