                        $line = str_replace($placeholder, str_repeat(' ', $delta).$placeholder, $line);

It seems like $delta can also be of type double; however, parameter $times of str_repeat() does only seem to accept integer, maybe add an additional type check?

                        $lines[$index] = $line;
                    }

            $tmpCode = str_replace($placeholder, '', implode("\n", $lines));
        }

        return $tmpCode;
    }
