[PHP-DEV] PHP 4.0 Bug #9563: realpath() returns empty string when working directory is under a symbolic link From: agreenbu <email protected>

Bug description: realpath() returns empty string when working directory is under a symbolic link

/opt/apache/htdocs is the Document Root for Apache.
/opt/apache/htdocs/directory is a symbolic link that points to /home/morespace/directory. Document /home/morespace/directory/username/index.php contains the code:

$RealPath = realpath(".");

if (!stristr($RealPath, $UserName)){
        echo "This directory does not belong to you. Attempt has been logged.";
        session_destroy();
        exit;
}

This code always fails because realpath(".") returns an empty string.
