realpath

Description

realpath() expands all symbolic links and resolves references to '/./', '/../' and extra '/' characters in the input path and return the canonicalized absolute pathname. The resulting path will have no symbolic link, '/./' or '/../' components.

realpath() returns FALSE on failure, e.g. if the file does not exists.

Example 1. realpath() example <?php $real_path = realpath("../../index.php"); ?>
