我在 php 中编写了一个基本循环，它可以满足我的需求，但现在我也在尝试添加一个链接，但无法获得正确的语法，并且我发现该语法的示例对我不起作用并且不断出现错误。如果有人能告诉我我哪里出错了，那就太棒了。提前感谢您是否能够提供帮助！

引发错误的代码是

<a href=\"addcomment.php?id="'. $row['postid'] .'\">' "Add Comment" '</a>");

完整的代码是。

<?php
    include("connect.php"); //connect to database
    //create query
    $get_messages_query = $db->prepare("
        SELECT * FROM `blogposts`
        ORDER BY `postid` DESC 
        LIMIT 5
        ");
    //Homepage should have last 5 blog posts this will take the //last 5 entered into the database and put them into an //array

    $get_messages_query->execute();
    //executes query above

    while($row = $get_messages_query->fetch())
    {
        $blog_post_history .=
        '<div class="post" id="post">
            <h1>'. $row['title'] .' </h1>
            <h2>' . $row['author'] . '</h2>
            <p>'. $row['content'] . '</p>
            <a href=\"addcomment.php?id="'. $row['postid'] .'\">' "Add Comment" '</a>");

        </div>';
    }

    // while loop that takes info from db query and puts the //information in its own div with title andauthor having a //unique heading for css as well as a p for the content of //the blog. This loop puts the information in //$blog_post_history which is called upon in the div code 
    //below
?>

这里的引号有问题

$blog_post_history .=
    '<div class="post" id="post">
        <h1>'. $row['title'] .' </h1>
        <h2>' . $row['author'] . '</h2>
        <p>'. $row['content'] . '</p>
        <a href="addcomment.php?id='. $row['postid'] .'">Add Comment</a>
    </div>';
