array problems

[doddsey_65]

i have a users online section and i am using an aray and implode so the comma is displayed on every username but the last, but it displays the same usernames several times. This could be due to the switch i am using to define user group. Heres the code:

 

$online_query = $db->query("SELECT user_id, user_group, user_username
                            FROM ".DB_PREFIX."sessions");
while ($online_info = mysql_fetch_object($online_query)) {

switch($online_info->user_group)
        {
            case 1:
                $userClass = 'admin';
                break;
            case 2:
                $userClass = 'mod';
                break;
            case 3:
            case 0:
            default:
                $userClass = 'user';
                break;
        }

$users2[] = "<span class=\"{$userClass}\">{$online_info->user_username}</span>"; 

echo '<p>' . implode(', ', $users2) . '</p>';
}

 

is there something i am doing wrong?

$users2 = array();

You have your echo inside the while() loop. Every time a value is added to the array, the updated array is imploded and the string is echoed.
