javascript与php的正确结合

这里没有什么帮助…我正在为一个消息系统编写一个php脚本。注释在php中通过函数使用$comments显示。我试图在javascript中使用一个灯箱，这样用户就可以选择删除每条评论。如何将以下php脚本与javascript代码结合起来：

<?php

$comments .= " <font size='3'>   ?>

<a href = "javascript:void(0)" onclick = "document.getElementById('light').style.display='block';document.getElementById('fade').style.display='block'">**Delete**</a>
    <div id="light" class="white_content">

        <form action="<?php=$_SERVER['PHP_SELF'];?>" method="post">
        <input type="submit" name="submit_1" value="Delete Photo" >
        </form>

    <a href = "javascript:void(0)" onclick = "document.getElementById('light').style.display='none';document.getElementById('fade').style.display='none'"><button>&nbsp;&nbsp;&nbsp;&nbsp;Cancel&nbsp;&nbsp;&nbsp;&nbsp;</button></a></div>
    <div id="fade" class="black_overlay"></div>             




<?php  $comments .= "</font>"; ?>

“method=“post”>

有两个语法错误：

1，您缺少第3行的结束双引号：

$comments .= " <font size='3'> "

$comments.=“”

2，

这样的方法应该行得通。记住“排爆药；“在一条线的开始，需要独立完成

另见

您正在尝试使用“？>html。。。“构造不正确。它不会“返回”字符串，而是直接打印出来——每当解析器经过它时，它将被发送到浏览器，而不是被添加到$comments中。
dot It…仍然没有任何结果。”
<?php

$comments .= <<<EOD
    <font size="3">
        <a href = "javascript:void(0)" onclick = "document.getElementById('light').style.display='block';document.getElementById('fade').style.display='block'">**Delete**</a>
        <div id="light" class="white_content">
            <form action="{$_SERVER['PHP_SELF']}" method="post">
                <input type="submit" name="submit_1" value="Delete Photo" >
            </form>
            <a href = "javascript:void(0)" onclick = "document.getElementById('light').style.display='none';document.getElementById('fade').style.display='none'"><button>&nbsp;&nbsp;&nbsp;&nbsp;Cancel&nbsp;&nbsp;&nbsp;&nbsp;</button></a>
