I got stuck on this and my brain is not working correctly. I am somewhat new
at PHP, and programming in general, so that is my excuse.
I am making an online reservations web page.

I have an array $rooms that has a list of room numbers.

I have another array $taken that has a list of the rooms that are not
available.

I want to find out which rooms are available by subtracting the items in the
$taken array from the $rooms array.

For instance,

If rooms has 1, 2, 3, 4, 5, 6, 7, 8

And the taken array has 3, 5, 8

How do I write the code so that I end up with an array called $available
that would have the remaining rooms 1, 2, 4, 6, 7?

Any help would be tremendously appreciated.

Thanks,
Kevin
