I've looked for something like this in the existing function suite but haven't found it...

Because Windoze and Linux (at least) use different characters to separate elements of a file path, I think a function that parses a path into an array of subdirectories, basename and extension would be useful.

I doubt this will ever appear in the language as it sounds more like a library 
function.
try using this for the OS-independent path parsing
    explode(DIRECTORY_SEPARATOR, $path);

Agreed, this sounds more like a library function that is better suited to be implemented in userland code.

We do have some cross OS compatible constants to help on that part:

DIRECTORY_SEPARATOR
PATH_SEPARATOR
PHP_SHLIB_SUFFIX

realpath() might also provide useful, as it normalizes a path to the OS path, meaning that:
realpath('/windows/system32')

Will convert into (on Windows):
%SystemDrive%\Windows\System32

And parse like that, second alternative we have is pathinfo() which does not validate the actual path but just parses it and works on any OS path, even mixes afair
