How to find out the id of other users?

Question

PHP

Hello, I have this script in my code

$link=mysqli_connect("localhost", "root", "", "test");
    $query = mysqli_query( $link, "SELECT * FROM `users`" );
    $userdata = mysqli_fetch_assoc($query);
       
echo "Номер: ".$userdata['user_id']."<br>\n";

He gets the user id from the database, but he gets exactly the id of 1 user how to make the rest?
