php realpath not producing usable outcome

<?php
    $server = $_SERVER["SERVER_NAME"];
    $pathpath = realpath("../../files/uploaded_file.jpg");
    echo "You can link to the file using the following link... $server$pathpath";
?>

Unfortunately this produces the following...

www.example.com/home/fhlinux123/g/example.com/user/htdocs/ninja/base/files/1.doc

Whereas what I am after is as follows...

www.example.com/files/uploaded_file.jpg

I can't assume that the folder 'files' will always be in the same directory.

That's because realpath returns the absolute path from the server box root, not the webserver htdocs root. You can retrieve the webserver htdocs root from $_SERVER["DOCUMENT_ROOT"], then strip that from the beginning of the result returned by realpath

Quick and dirty example:

$server = $_SERVER["SERVER_NAME"]; 
$pathpath = realpath("../../files/uploaded_file.jpg"); 
$serverPath = $_SERVER["DOCUMENT_ROOT"];
$pathpath = substr($pathpath,strlen($serverPath));

echo "You can link to the file using the following link... $server$pathpath";
