DirectoryIterator::getBasename vs DirectoryIterator::getFilename

Question

Is there any difference between getBaseName and getFilename when called with no arguments?

Answer 1

As far as I know there is no difference except that getBaseName has a single parameter to cut suffix's of the file name. No significant difference. Although the Base suggest something more - I am quite sure it points to being able to cut things off at the end and nothing more.
