Get array of directories?

[goldingdamien]

I am already using this library and would like to request the following feature.

=== Feature request ===
Details: Function to get an array of directories.
Example: http://example.com/dir1/dir2/dir3/index.html?q1=v1 => [dir1, dir2, dir3]
Contribution: If it is difficult to add this future in the near future, I am willing to make the contribution.

*Not as important, but a function to get the file name and file extension separately would be useful.
Thank you.
