The problem that you encountered is not the problem that you stated it
was. Your error[1] was the failure to understand the difference between
an http url and a filesystem path.
The webserver translates the http url to the filesystem path, where the
"root" directory of the webserver "www.something.com" might be at a file
path that looks something like "/users/s/something.com/http/"
For example, on a fasthosts uk server, using apache, the root of the http
files is available as: {$_SERVER["DOCUMENT_ROOT"]}
Your problem is that you were trying to use a url as a filepath.
What you need to do is take the url:
http://www.something.com/dir/
replace the part: "http://www.something.com" with "{$_SERVER
["DOCUMENT_ROOT"]}"
then append the path part of the url: "/dir/"
then append your $variable
To generate:
$dir = "{$_SERVER["DOCUMENT_ROOT"]}/dir/{$variable}"
