realpath

(PHP 4, PHP 5)

realpath -- Returns canonicalized absolute pathname

Description

string 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 exist. On BSD systems realpath() doesn't fail if only the last path component doesn't exist, while other systems will return FALSE.

Example 1. realpath() example

<?php
chdir
('/var/www/');
echo
realpath('./../../etc/passwd');
?>

The above example will output:

/etc/passwd
