It seems like you are loosely comparing $encoding of type null|string against null; this is ambiguous if the string can be empty. Consider using a strict comparison !== instead.

                print "<PRE>\n".htmlentities($message, $flags, $encoding)."\n</PRE>";
            } else {
                print "<PRE>\n".htmlentities($message, $flags)."\n</PRE>";
