Actually, this will work just fine.

Very rarely, it's generally clearer to use an array if you want to keep 
the variable for later, or just unset/reuse it.

ie:

$users = array();
foreach ($signups as $id => $signup) {
   $users[$id] = new User();
   $users[$id]->register();
}

or:

foreach ($signups as $signup) {
   $user = new User();
   $user->register();
   unset($user);
}

the call to unset is optional, if you leave it out the variable $user 
will be overwritten on each iteration through the loop.
