Thanks for the input :) It's one of those "am-I-losing-my-marbles?" sort of
situations and it's good to have feedback confirming my logic!

If you want to perform an operation on every member of an array using 
foreach, you can do:

foreach ( array_keys($array) as $key ) {
	$array[$key] =& myfunction($array[$key]);
}

As always there are any number of ways to skin a cat, if you just wanted 
to increment every member of an array you could do:

foreach ( $array as $key => $val ) {
	$array[$key]++;
}

which is equivalent to:

foreach ( array_keys($array) as $key ) {
	$array[$key]++;
}
