How to add a unix user using php?

[Anon]

Hi
I have this sample code below :

<?php
$username = "edselle";
$password = "mypasswd";
system("useradd $username");
system("echo '$password' | passwd --stdin $username");
?>

I've got it to work if i use this as a php shell script and running as root, but when i run it on the web browser it doesn't output anything and the user that i'm expecting to be created was not successfully created. Do i miss something here. This could be an access rights problem right? What do i need to add to this piece of code so that i would be able to run it successfully on the web browser?

Only root can add users and only root can change passwords other than it's own.

Write your new-user data to a textfile.
Make a new script that reads this textfile and creates the users.
Put the new script in the contab of root to have it run every X minutes, or check out the "sudo" program.
