在带有转义字符（双引号）的对象上使用 json 编码

Question

I am using mysqli::real_escape_string on the inputs received from my forms before sending them to the database .在将它们发送到数据库之前，我在从我的表单接收到的输入上使用mysqli::real_escape_string 。
in another page i am receiving these data and converting each row of data into JSON using json_encode在另一个页面中，我正在接收这些数据并使用json_encode将每一行数据转换为 JSON
then i am sending them into front-end as response :然后我将它们发送到前端作为响应：

        $usersInstance = new usersRepository();
        $users = $usersInstance->allUsers();  
ob_start();  
 foreach ($users as $index => $user) {

                $userObj = (object) [];
                $userObj->id = $user['id'];
                $userObj->email = $user['email'];
                $userObj->displayname = $user['display_name'];
                $userObj->grade = $user['grade'];
                $userJson = json_encode($userObj);
                $userBox = <<<HTML
            <div class="user-box" data-userjson={$userJson}>

<div class="user-cell " >
    <span> {$user['email']} </span>
</div>

<div class="user-id-holder"  style="visibility:hidden;width:0px;height:0px;overflow:hidden;display:inline-block">
 {$user['id']}
</div>

<div class="user-cell" >
    <span>{$user['display_name']}</span>
</div>
<div class="user-cell " >
    <span>سطح دسترسی : {$user['grade']}</span>
</div>
<div class="user-cell">
    <span class="user-action-btn" data-action="edit"><span>ویرایش</span></span>
    <span class="user-action-btn" data-action="delete"><span>حذف</span></span>
</div>
</div>
HTML;

                echo $userBox;
            }
            $renderedContent = ob_get_contents();
            ob_end_clean();

then i want to access these JSONs in javascript like this然后我想像这样在javascript中访问这些JSON

let UserBox = $(this).parent('div').parent('div.user-box');
let userObj = $(UserBox).data('userjson');

The problem is that when i try access object i get errors and undefined because escaped double quotes represent as " and it makes the object an invalid JSON , see example output below :问题是，当我尝试访问对象时，我得到错误和未定义，因为转义的双引号表示为"并且它使对象成为无效的 JSON ，请参阅下面的示例输出：
{"id":"32","email":"test3@gmail.com","displayname":"test'and'more'test"","grade":"2"}
displayname propert has a value that contains double quote which cause object to be invalid. displayname属性的值包含双引号，导致对象无效。

My question is that how can i keep escaped characters escaped when i am using the JSON i want to display the values in html and they become " when are printed . so actual problem is that how can i seperate " and &quot ?我的问题是，当我使用 JSON 时如何保持转义字符转义，我想在 html 中显示值，并且它们变成"何时打印。所以实际问题是我如何将"和&quot分开？

Use htmlentities to escape the quotes and turn them into "使用htmlentities转义引号并将它们转换为" when handling your form data.处理表单数据时。 Then when you get the data back and use json_encode on it, there should be real double quotes around your JSON stuff and the quotes going in the HTML are "然后，当您取回数据并在其上使用json_encode时，您的 JSON 内容应该有真正的双引号，并且 HTML 中的引号是" , which will be properly parsed and rendered. ，它将被正确解析和呈现。
