What is the difference between realpath() and is_dir() in php?

What is the difference between realpath($path) and is_dir($path)?

I know realpath follows symbolic links, but is there a performance difference between the two?

How about looking at the manual.

realpath — Returns canonicalized absolute pathname

is_dir — Tells whether the filename is a directory

Realpath returns the canonicalized actual pathname of a file on success, is_dir returns a boolean value of whether or not the file is a directory.
