我正在拼命地朝着 OOP 方向发展,但我不知道什么时候使用它。我得到了机制,但何时使用它们只是不点击。我很好奇我目前的情况是否适合 OOP 方法。
我有 3 页。Details.php 显示两个并排的 div。一个用户可以添加注释,另一个可以查看存储在 MySQL 中的以前的注释。他们可以通过 Details.php 中的 AJAX 功能添加注释和提取注释。javascript 函数调用 add_notes.php 向数据库添加注释,并调用 load_notes.php 通过 Jquery .load() 在页面上加载注释以及提交新注释以刷新 div 时。
我是一个新手,但我觉得有更好的方法来组织这段代码。我会研究一个框架,但我已经深入到这个项目中,所以正在寻找关于如何更好地分解它的 OOP 想法或验证我正在以尽可能简化的方式进行操作。所有评论都有帮助!

// All the variables from the submission form
$notes = filter($_POST['notes']);

//Insert Notes into the database
$stmt = $dbh->prepare('
INSERT INTO `notes`

$stmt->bindValue('notes', $notes);
$stmt->execute();
echo "This note was added successfully";
