Question

Hi as I mentioned in last question that I am learning class and method in php so I have another problem to understand how to use this query method to output the result in theme.

I am trying with WordPress at the moment so please consider it. However it is not too generic with WordPress rather the logic.

<?php

class get_user_widget
{

    // other mentods are here which is not related to below method

    public static function get_users() {
        global $wpdb;        

        $query = "SELECT id, user_login FROM $wpdb->users ORDER BY user_registered DESC";
        $users = $wpdb->get_results($query);

        // here I am using foreach so is it okay or while loop is right to use?
        foreach ($users as $users)
            $rs[] = $users;

        return count($rs) ? $rs : array();

    }

}

?>

So how can I use this in theme to render the output list of user by registered date? I have checked with print_r() and connection and everything is fine and getting output in array but need to use html.

Thanks a lot..

The class can be used like this:

$array = get_user_widget::get_users();
echo "<ul>";
foreach($array as $user) {
echo "<li>".$user->user_login."</li>";
}
echo "</ul>";

EDIT:

class get_user_widget
{

    public static function get_users() {
        global $wpdb;        

        $query = "SELECT id, user_login FROM $wpdb->users ORDER BY user_registered DESC";
        $users = $wpdb->get_results($query);


        if(!empty($users)) {
             return $users;
        }
        else {
             $fakeuser = new stdClass();
             $fakeuser->user_login = "No users in database";
             return array($fakeuser);
        }
    }

}
