    $numbersLength = count($numbers);

    for ($i = 1; $i <= $limit; $i++) {

            if ($index >= $numbersLength) {

            }

var_dump(multiple_cycle(1000000000, array(5395, 7168, 2367, 9999, 3)));

Good first try, and you should get the right answer for smaller values of $limit. The question asks for the number of cycles required to reach $limit using multiples of the values in $numbers, right? Instead of counting up from 1 to $limit by 1, try incrementing by the values in $numbers instead.
