wp_basename() │ WP 3.1.0

Gets the last component from the specified path or URL, retrieving everything after the last /.

This is a copy of the PHP function basename(), only it is localization-friendly (l18n).

It is recommended to use when obtaining file names passed via GET, POST parameters, or retrieved from the database. In other cases, use basename() - it is slightly faster.
