Quick and easy optimization (not considering the other changes you are asking about): Replace

    return 1;

From your coded logic, there is no reason to continue looking through the rest of the array if you have found a match. You can also drop the declaration of $within and end the sub with 
    return 0;

since no match was found if it finishes the loop.
