mmmm, path dependency...

So, what do you recommend instead, then, that wouldn't use
document_root? Saying 'switch hosts' doesn't help much, as it's not
gonna happen.

that's about all you're going to get from jerry. :)

i'll repost this:

$parsedUri = dirname($_SERVER['PHP_SELF']);
$parsedUri .= substr($parsedUri, -1) != '/' ? '/' : '';
$relativeUri = str_replace('/', '', $parsedUri);
$relativePath = strlen($parsedUri) - strlen($relativeUri) - 1;
if ($relativePath < 0){ $relativePath = 0; }
$relativePath = str_repeat('../', $relativePath);
if (!$relativePath){ $relativePath = './'; }
?>

name that whatever you will...say, relative.path.php, for instance. put that
script in your php include_path. from there, it doesn't matter where your
parent script is run. you get document_root in relative terms regardless of
what your server's configuration is. to implement this, just do this at the
top of your parent script:

require_once 'relative.path.php';
include_once $relativePath . 'name of other script to include here';
// rest of code
?>

hth,

me

Why now? If you can't get what you need from your current host, there
are thousands who will give you want you need.

You could parse the URL being used and count the number of directories
down you are. Then you could parse __FILE__ to get your absolute
directory. Then back up to get to your root directory. But that has
its own problems, and can leave you open to hacking attempts.
