如何用toastr和php-mysql创建动画预警系统

大家好,我想用toastr和PHP MySQL创建动画通知系统,但我不知道该怎么做。我已经在我想要创建的页眉和页脚文件中集成了jQuery Toastr插件,如下图所示

This is example Image

我是新来的,所以我不明白我怎么能做到。请帮帮我。

下面是我的html和PHP代码。请告诉我如何调用成功消息、警告消息和错误消息。

<?php include_once('inc/header.php');
$database = new Database();

$db = $database->getConnection();

$addmouja = new Mutation($db);

?>
