Regular Expression to match a Windows (Local and UNC) or UNIX Path

I've been looking for a regular expression (regex) to get a path, file name and extension from a full UNIX path for a small app I'm working on but could only come across Windows ones.

For anyone looking, here I've come up with what I was looking for: A regular expression to match a Windows (Both UNC and Local paths) or UNIX paths as well as breaking that path into it's relavant segments all in one go.

Regular Expression:

^(.*?/|.*?\\)?([^\./|^\.\\]+)(?:\.([^\\]*)|)$

PHP Function Example:

// Split filepath path, name and extension
function namesplit($path)
{
preg_match('@^(.*?/|.*?\\\\)?([^\./|^\.\\\\]+)(?:\.([^\\\\]*)|)$@', $path, $namesplit);
return $namesplit;
}

Output Example:

Array
(
[0] => /path/to/file/filename.ext
[1] => /path/to/file/
[2] => filename
[3] => ext
)

I hope this saves someone some time!
