PHP 记录访客的浏览信息方法

可以记录访客的地理位置，操作系统，浏览器，IP，时间和访问的文件。

1.首先创建一个comm_function.php文件：

<?php
//echo $_SERVER['HTTP_USER_AGENT'];
//echo "<br />".$_SERVER ['REMOTE_ADDR'];
/**
* 获取客户端类型，手机还是电脑，以及相应的操作系统类型。
*
* @param string $subject
*/

 $filename = "./log.log";
 if (! file_exists ( $filename )) {
   fopen ( $filename, "w+" );
 }
 file_put_contents ( $filename, $data, FILE_APPEND );
}

2.在别的文件引入这个comm_function.php

require_once "comm_function.php";
