I used this php file put in a subdir below document root:

<?php
$rootdir= substr(__DIR__, 0, strpos( __DIR__, 'htdocs')) . 'htdocs';
echo "Root dir: " . $rootdir . "<br>";
echo "Real root path: " . realpath($rootdir) . "<br>";
$docroot=$_SERVER["DOCUMENT_ROOT"];
echo "Document root: " . $docroot . "<br>";
echo "Real document root: " . realpath($docroot) . "<br>";
include ($rootdir . '/php/logindata.php');
echo "Mail sender using Real root path: " . $mailsender ;
?>

The printed output whan I call this php file with FireFox:

Root dir: /data/25/2/158/91/2484743/user/2721122/htdocs
Real root path: /data/25/2/158/91/2484743/user/2721122/htdocs
Document root: /usr/services/vux/apache/htdocs
Real document root: /usr/services/vux/apache/htdocs
Mail sender using Real root path: [email protected]

Notice that the two paths grabbed by __DIR__ and $_SERVER["DOCUMENT_ROOT"] are
clearly different and using the latter in the include will make the $mailsender
variable empty.
