It seems like $lines can also be of type false; however, parameter $var of count() does only seem to accept Countable|array, maybe add an additional type check?

            return '';
        }

        // Toss out the first and last lines.
        $lines = array_slice($lines, 1, count($lines) - 2);

        // take the tabs form the first line, and subtract them from all lines
        $matches = [];

        for ($i = 0; $i < count($lines); $i++) {

It seems like you are calling the size function count() as part of the test condition. You might want to compute the size beforehand, and not on each iteration.

            $lines[$i] = str_replace($matches[0], '', $lines[$i]);
        }

        return implode("\n", $lines);
    }
