PHP-访问者在线柜台 [英] PHP - Visitors Online Counter

问题描述

我有以下代码来统计PHP网站上的访问者。在使用WampServer的本地开发计算机上，它可以正常工作，但是当我将文件上传到托管帐户进行测试时，我意识到它无法正常工作。

I have the following code to count visitors on my PHP site. It works fine on my local development machine using WampServer but when I uploaded my files to my hosting account for testing I realized that it does not work properly.

我的满意度很高数字计数，并且还注意到会话从未删除，因此它们只会不断累积。

I get really high number count and also noticed the session are never deleted so they just keep accumulating.

这是一个简单的会话计数器。有更好的方法吗？可以请一个人给我看一下还是指点什么？ 谢谢！

It is a simple session counter. Is there a better way of doing it? Could some one please show me or point me to some article? Thank you!

<?php
//------------------------------------------------------------
// VISITORS ONLINE COUNTER
//------------------------------------------------------------
if (!isset($_SESSION)) {
  session_start();
}
function visitorsOnline()
{
    $session_path = session_save_path();
    $visitors = 0;
    $handle = opendir($session_path);

    while(( $file = readdir($handle) ) != false)
    {
        if($file != "." && $file != "..")
        {
            if(preg_match('/^sess/', $file))
            {
                $visitors++;
            }
        }
    }

    return $visitors;
}
?>

推荐答案

如果您想要自己的内部计数系统，那么我会建议，将与网站有关的信息存储在数据库中。并在用户每次浏览网站时更新记录。

If you want your own internal counting system then I would suggest, storing such information related to website in database. And update the record everytime a user browses the website.
