所见即所得文本编辑器在查询中显示不好

我遇到了一个问题，我将CKeditor集成到了我的CMS中，当我将一些文本复制到查询中时，在

之后显示一个<'h2> <'p>，然后如果有人试图删除这些统计信息，在我删除后，它在页面上显示了更多的<'h2> <'p>

<'p>
 <'p>
 <'p>
 <'p>

page.php

// Query the body section for the proper page
    $stmt = $con->prepare('SELECT pagebody FROM travel WHERE link = ?');
    $stmt->bind_param('s', $pageid);
    $stmt->execute();
    $result = $stmt->get_result();
    while ($row = $result->fetch_array()) {
        // do something with $row
        $body = htmlspecialchars_decode(stripslashes($row['pagebody'])); //pentru caractere speciale
    } <?php echo $body; ?>

//编辑页面
