realpath ( string path )
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");
