note 48810 deleted from function.dirname by danbrown

Note Submitter: not AT available DOT com ---- There is no distinction between a directory and a file. This is how dirname() and basename() work. A directory *is* a file. There is no such thing as a path to a non-existing file. The path '/home/users/bob/' refers to the file 'bob' in directory '/home/users/', not the file '' in directory '/home/users/bob/'. This is trivial. Given the path '/etc/conf/sample', there is no way of determining whether 'sample' is a file or a directory just by looking at it. Think about that.
