foreach sort of asbtracts away some of the complexity and is
usually easier. I use this whenever I don't need to know the
numeral index of the array or $key => $value won't provide
me with it.

for is the older C style where you must first perform a
count() so you know how many iterations the loop requires.
It is useful when you need to know the index, or to count
backwards or step through in different groups.
