First, upgrade to PHP5 ;-)
(Remember that PHP4's end-of-life is near, BTW)
Second, modify the array elements by using the array name and the relevant
key:
Instead of
foreach ($array as $key=>&$item)
{
$item['foo'] = $whatever;
}
use something like:
foreach ($array as $key=>$item)
{
$array['key']['foo'] = $whatever;
}
*And* leave a nice comment about changing that when upgrading to PHP5. Don't
forget about those little things, try to keep your code clean.

Referencing stuff is not that complicated (it gets very easy if you know are
trained in C pointers), but it's pretty good to handle situations like
this, and it's indispensable if you want to do semi-complex stuff with
classes and objects.
