Checking if file is on localhost or not, implent optional argument to file_exists() ?

Since PHP5 many/most filesystem functions can be used with "some" URL wrappers.

That's good and all but now it's quite difficult to check if file is on localhost or not.

It´s possible to use `parse_url()` and check if "scheme" is set for instance but I belive we should insert new optional argument to `file_exists()`, `is_file()` and `is_dir()` etc.

example;
bool file_exists ( string filename [, bool strict ] ) where strict is default to false but when true only check if filename exists on localhost.

Agree? Or is there a simpler/better way of doing this?
