The relation between array_reduce and scalar type hints is that API start to enforce certain types where they should not just because the programmer thinks it is a good idea. Currently the third parameter $initial of array_reduce only allows int. So instead of allowing any zval and leaving it to the callback function to deal with it a specific type is enforced. You can work around this by checking for NULL inside the callback and initializing it there but that does not work either if you use a built-in function as callback. - Chris
