PHP working for me. Maybe they fixed it.

I enjoyed this one. Great tests. This is a good problem for test driven development, and it shows. Two suggestions:

• State more explicitly in the problem that going out of bounds wraps around. The test for this was called "toroidal", but I didn't know what that meant.
• This problem seems more difficult than 4kyu. Personally I'd peg it at 3kyu or 2kyu.

Thanks.

It's already been approved.

PHP version might need more secret test cases. Answers like this are getting through. If I'm reading the kata right, there were only 2 tests I think.

function validate_battlefield(array $field): bool {
  $result = rand(0, 1);

  return $result;
}

; rdi = array (pointer)
; esi = size (unsigned int)
