Thank you very much.

I was not able to get DOCUMENT_ROOT or any other server variables. All was returning empty.

I used this and it's working. I modified

$path = ""; for($i=count(explode("/",dirname($SERVER['PHPSELF']))); $i>1; $i--) $path .= "../"; echo $path;

this works from root folder itself and any level of subfolders

Thanks again

Thanks for the code, though it doesn't seem to work for me. It always returns "../" whether I'm 1 or 2 directories deep.

This code doesn't work. After about an hour and a half of painful searching and failed techniques, I came up with the following code snippet that DOES work under all circumstances, even when you have malformed paths such as http://www.blah.com////path//to///file.php $relpath = ""; $tempvar_relpathdir = explode("/",dirname($_SERVER['PHP_SELF'])); for($i=count($tempvar_relpathdir); $i>0; $i--) if($tempvar_relpathdir[$i] != '') $relpath .= "../"; Hopefully since this is the first result that comes up on google, this will save the pain of others in the same situation.

[code:] function spec_root($root=NULL) { $cur_file = $_SERVER["SCRIPT_NAME"]; $cur_file = explode('/', $cur_file); $cur_file = $cur_file[count($cur_file) - 1]; $tmp = split($root, $_SERVER['REQUEST_URI']); $tmp = str_replace($cur_file, "", $tmp); $tmp = $tmp[1]; $tmp = str_replace('\\', '/', $tmp); $tmp = explode('/', $tmp); $relpath = NULL; for ($i = 0; $i < count($tmp); $i++) { if ($tmp[$i] != '') { $relpath .= '../'; } } if ($relpath != NULL) { $relpath = substr($relpath, 0, -1); } else { $relpath = '.'; } return $relpath; } [code]

I don' t understand how you're supposed to post code as comment -- sorry. My previous comment extends on asherber's example. The function removes the currently executing script name and allows you to specify a root folder.
