You're not using the keys in foreach, so why you need to preserve them?

This may be not so easy to implement - imagine passing $array[*1:4] by
reference. You should be able to do so, since $array[*1:4] is an lvalue
for you, but what would you pass? What if $array changes in the
meantime? There's a big can of worms here. And you already have
array_splice which doesn't have these issues.
