编辑三-其中我们发现我真的不是很聪明的
虚惊人，我不能使用php在我目前的设置。我要去把头撞在墙上一段时间。无论如何，谢谢你的帮助和建议。
我试图遵循这教程，以便允许在我的响应网站上的“移动/满”开关。但是，用于显示选项的链接是同时显示这两个选项，而不是像它应该显示的那样出现“任意一种”的情况。
本教程使用的是一些PHP，我还不知道，所以我不知道错误在哪里。在我看来一切都很好，但这段代码：
<div id="toggleView">
<?php if ( $fixedwidth == '1' ): ?>
<a href="<?php echo $_SERVER["SCRIPT_NAME"] ?>?fixedwidth=0">Switch to Mobile site</a>
<?php else: ?>
<a href="<?php echo $_SERVER["SCRIPT_NAME"] ?>?fixedwidth=1">Switch to Full site</a>
<?php endif; ?>
</div>应该只显示其中一个字符串，但相反，它会显示以下两个链接：
?fixedwidth=0">Switch to Mobile site ?fixedwidth=1">Switch to Full site
我认为这是["Script_Name"]段的语法问题，但我不知道正确的语法应该是什么。

这是我在页面中插入的用于检测fixedwidth中的变化的PHP
<?php
$fixedwidth = '';
// Check if the query string contains our key and assign its value to $fixedwidth
if ( isset($_GET['fixedwidth']) && ($_GET['fixedwidth'] != "") ) {
$fixedwidth = $_GET['fixedwidth'];
}
// Check if a cookie has already been set
if ( isset($_COOKIE['fixedwidth']) ) {
if ( $fixedwidth == '0' ) {
// If the value is '0', delete the cookie
setcookie('fixedwidth', '', time() - 60, '/');
} else {
// Value is not '0', so no need to get the cookie value
$fixedwidth = '1';
}
} else if ( $fixedwidth == '1') {
// The user wants fixed width, so set a cookie
$expires = 60 * 60 * 24 * 60 + time();
setcookie('fixedwidth', '1', $expires, '/');
}
?>所以，我基本上复制了这个教程中的内容，试图在我的页面上获得这个功能，但我不知道它是否真的正确。

为了使这是一个真正的答案，从注释和编辑中可以看到，您正在尝试将PHP代码编写到设置为C#的ASPX文件中，这就是它无法工作的原因。
您需要使用ASP.NET的模板语法而不是PHP重写它。

条件词没有使用适当的PHP语法。
这里有一个固定版本：
<div id="toggleView">
<?php if ( $fixedwidth == '1' ) { ?>
<a href="<?php echo $_SERVER["SCRIPT_NAME"] ?>?fixedwidth=0">Switch to Mobile site</a>
