PHP 记录访客的浏览信息方法

$time = date ( 'y-m-d h:m:s' );
$data = "来自{$country} {$province} {$city }{$nettype} 的客户端: {$client_info},IP为:{$clientip},在{$time}时刻访问了{$_SERVER['PHP_SELF']}文件！rn";
$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
