On click on link page will refresh then you can use php GET to get page name and set active class on li as below :

<?php

if (isset($_GET['site'])) {
    switch ($_GET['site']) {
        case 'ban_add':
            $activeClass1 = 'active';
            break;
        case 'ban_add_online':
            $activeClass2 = 'active';
            break;
        default:
            $activeClass = 'active';
            break;
    }
}
?>

<li class="<?php echo $activeClass; ?>"><a href="admin.php" >{"_MENUINFO"|lang}</a></li>
<li class="<?php echo $activeClass1; ?>"><a href="admin.php?site=ban_add">{"_ADDBAN"|lang}</a></li>
<li class="<?php echo $activeClass2; ?>"><a href="admin.php?site=ban_add_online">{"_ADDBANONLINE"|lang}</a></li>
