mkdir() problem

[lewis987]

i want to make a folder everytime someone registers using the mkdir() function

 

$host = "localhost";

$user = "root";

$pass = "lancer";

$db  = "login";

$ID = '';

$USR = $_POST["usr"];

$PWD = md5($_POST["pwd"]);

$MD = mkdir("website/upload/$USR");

 

but the variable doesnt work within the string some some reason

 

any help appreciated
