#13490 — scandir problem

http://www.php.net/manual/en/function.scandir.php

Using their method, what is the proper way to insert a variable within the
url?

e.g.
http://www.something.com/dir/$variable

Is the ending / needed?
this does not work.
$dir="http://www.something.com/dir/$variable"
$dir="http://www.something.com/dir/".$variable

I did get it working by using the ".." before the path.
Apparently, the full url method does not work in this case.

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}"
