Loop Iteration in Php Game

Trying to allow the user to guess at "1" movie, three times, if they dont get it, it tells them the right answer (which is variable: $rand_keys). It also deducts guesses and displays the amount of guesses left (possible error with $guesses variable?).

Whats going wrong here? Please show me a possible solution.
