我正在尝试创建一个基于会话的计数器。而且我的代码似乎不起作用。每当,我重新加载页面。输出是“你已经浏览了 0 次页面”。
<head>
<meta http-equiv="Content-Type" content="text/html; charset=UTF-8" />
<title>Untitled Document</title>
</head>
<body>
<?php
session_start();
if(!isset($_SESSION['count']))
$_SESSION['count'] = 0;
else
$_SESSION['count']++;
echo "You Have Viewed this page ", $_SESSION['count'], " times.";
echo session_id(); ?>
</body>
</html>
什么时候,我在我的本地主机上运行这段代码。代码根本不起作用。当我在我的网络服务器(hostgator)上运行它时,我得到以下错误。

请给我有关如何修复此错误的详细信息。非常感谢你。
