I wish it was that easy but associative arrays are like 'hash tables' so the
values will not be in the proper order.

Even "numeric" arrays are just a hash table. There's no built-in order
of array elements. By default all elements are stored and retrieved in
the order in which they are inserted:

$foo = array(2 => 'foo', 1 => 'bar');
var_dump($foo);

If you want a "correct" order, you always have to use one of the various
array sorting functions.
