Actually, I think this approach might be the most elegant and still
keeping the previous order. It assumes that there is an array $replace,
which maps the current key to the one it should be replaced with.

$keys=array_keys($array); // extract keys
$values=array_values($array); // extract values
foreach ($keys as $i=>$key) $keys[$i]=$replace[$key]; // replace
$array=array_combine($keys,$values); // map back together

This is just off the top of my head and untested - it should work
according to what I read on the php.net pages, but I haven't tried it out.

array_keys and array_values maintains the current order of the array,
however, so the keys should be mapped to the same values as before.
