JavaScript tests allow RegExp objects with non-escaped strings to pass, where substrings like "[" would fail.
This should be tested or substr should be specified as only having alphanumeric characters in the description.

Are you sure the random tests in PHP are correct? I believe I am using the exact same logic in both Javascript and PHP but my PHP solution is failing a few random tests (my Javascript solution is fine). I printed $m, $n and $position for debugging and found out that my solution does not agree with the official solution used in the random tests when $position['x'] === $n or $position['y'] === $m where I believe the coordinate is just out of bounds. The output by the official solution used in the random tests also confirms this fact as there is no "*" character in the output in such cases; however, "1"s still appear in the expected output.
