Question

我在我的脚本上注释了PHP评论。但它们仍以HTML格式显示在我的网页上。你知道我该如何解决这个问题吗？

亲切的问候，

/*if (isset($_POST['submitted'])) {
//require_once is similar to 'include' but ensures the code is not copied multiple times
require_once('LoginFunctions.php');*/

此文字显示在我的网页上：

我的整个剧本：这是我的整个脚本，因此您可以确定错误的位置。

Answer 1

在PHP代码部分中注释它们

<?php /*  code here will not display in html */ ?>

<!-- code here will be visible (in view source) -->

如果您的php解释器没有在那里运行，则无法隐藏php代码。

Answer 2

你在行

中忘记了一个"

echo '<div id = "div_1><h1>Login</h1>';

显然导致它以某种方式继续回应之后发生的事情。

解决方案：在"

之后添加缺少的div_1
