Perhaps you need to use http://php.net/reset
You see, when you do foreach or each or any of those, there is an
"internal" setting in the array that is altered to keep track of where you
are. Kind of like a big "You are here" arrow inside the guts of the
array.
If you've gone through the whole thing already, you have to reset the
internal point back to the beginning.
"Be Kind, Rewind!"
TIP:
Put a 'reset' before anything that loops the array. That way, if you add
something before it that loops through, it can't cause the side-effect of
a bug in your other code. Just a good habit to form.
