How to get folder name from url address

Question

URL of my site is:

http://mc.net46.net/ + folderName + fileName

For example:

http://mc.net46.net/mc/file01.php
http://mc.net46.net/mx/file05.php

folderName is always two characters long.

$address = 'http://mc.net46.net'.$_SERVER["REQUEST_URI"];

result: http://mc.net46.net/mc/file01.php - ok

$fname = substr($_SERVER["SCRIPT_NAME"],strrpos($_SERVER["SCRIPT_NAME"],"/")+1);

result: file01.php - ok

Two questions:

Is this the correct way to get $address and $fname ?

How to get folderName?

Answer 1

Try this for another way to get your dynamic file names:

    <?php

    $fname = "http://mc.net46.net/mc/file01.php";
OR 
    $fname = $_SERVER["REQUEST_URI"];
    $stack = explode('/', $fname);
    $ss = end($stack);
    echo $ss;

    ?>

Here for $fname you can use this $fname = explode('/', $_SERVER["REQUEST_URI"]);
