将文件上传到Web根目录之外

Question

i want to upload images outside web root directory, but i don't know how to do it.
For example i want to put images in var/media3/ , i set the media directory to permissions 777, now i need to modify the code to put images because that can not work.
I tryed even using $_SERVER['DOCUMENT_ROOT'] but it doesn't work (and honestly I have never tried this kind of thing).

This is the upload.php script:

<?php

// A list of permitted file extensions
$allowed = array('png', 'jpg', 'gif');

if(isset($_FILES['upl']) && $_FILES['upl']['error'] == 0){

    $extension = pathinfo($_FILES['upl']['name'], PATHINFO_EXTENSION);

    if(!in_array(strtolower($extension), $allowed)){
        echo '{"status":"error"}';
        exit;
    }

    if(move_uploaded_file($_FILES['upl']['tmp_name'], 'var/media3/'.$_FILES['upl']['name'])){ // <--The problem is in this string, it won't work
        echo '{"status":"success"}';
        exit;
    }
}

echo '{"status":"error"}';
exit;

Thanks XD
