Only thing to note with the foreach is that you are actually working on
a copy of the array, so if you intend to modify it, pass it by reference.

Can you do that? I assume it would look like this:
foreach(&$array as $a) {}
Close. It actually looks like this:
foreach ($array as $key => &$value) {}
This makes sense because for each iteration of the loop, PHP places a
copy of the key in $key, and a copy of the value in $value. Therefor,
you are specifying with this code that you want it to place a reference
of the value into $value.
