[Bug] Protein Translation exercise does not complete

Hello, I hope this is the right place to post this.
I am working my way through the PHP track and I believe I solved the exercise Protein Translation properly. All tests pass, but somehow I still get the warning “0 test failures” and I am unable to complete this exercise. My solution is in accordance with community solutions and the little number of submissions makes me believe I am not the only one who can not complete this exercise, while having all tests on green.

I believe this is a duplicate of Some PHP exercises can't be submitted via the online editor - #10 by Eggman

@neenjaw is going to fix it, but has been very busy with his own stuff recently, so it’s taking a little while to get done.

Sorry for the pain :slight_smile:

I have a PR now ready for review to fix this issue. Sorry for the delay.
