I have a short function ... and it tags "$error" as unused, whilst it is used within the string ${error['index']} construct function getErrorString($errorList) { $str = ""; foreach ($errorList as $error) { $str .= "[errno ${error['errno']}]\n"; } return $str; } It appears to be that indexed variables in conjunction wiht the ${...} construct provokes the problem. Just using $error works as expected (no hint), as does ${error} and $error[1]. But ${error[1]} provokes it to be shown.
