Question

I am building an entire system using PHP and MySQL.

I want to create usergroups.

For example
I want ADMIN1 to be able to ADD USER, and REMOVE USER

BUT

I want ADMIN2 to be able to ADD USER only

What is the standard way to do this?

Thanks.

You could use a simple login system and use sessions to allow access to certain pages e.g.

session_start();
if (!(isset($_SESSION['login']) && $_SESSION['login'] != '')) {
header ("Location: login.php");
}

This example just stops the user from accessing any other pages without first logging in. The login page would change the session like so:

        if (!empty ($username) && !empty ($password)){
        $sql = mysql_query ("SELECT * FROM users WHERE username='".$username."' AND password ='".$password."' LIMIT 1");
        if (mysql_num_rows ($sql) > 0){
            $_SESSION['login']=1;
            $_SESSION['username']=$username;
            header ("Location: index.php");
        }

That’s just a basic example but hopefully you can see what can be done using a user’s table and sessions 🙂
