这种一款可以统计你网站当前在线人数的代码哦,由php+txt实现的无需数据来来支持。
$time = gettimeofday(void);
//文件初始化 start
if(@filesize("time.text")
$fd_time = fopen("time.text","w+");
fputs($fd_time,$time[sec]);
fclose($fd_time);
$fd_time = fopen("ip.text","w+");
fclose($fd_time);
}
//文件初始化 over
//更新时间 start
$tamp = file("time.text");
$equal = ($time[sec] - $tamp[0]);
if($equal > 60){
$fd_time = fopen("time.text","w+");
fputs($fd_time,"");
fclose($fd_time);
}
//更新时间 over
//检查ip start
$fd_ip = fopen("ip.text","a+");
//获取用户ip地址
if ($http_server_vars["http_x_forwarded_for"])
{
$ip = $http_server_vars["http_x_forwarded_for"];
}
elseif ($http_server_vars["http_client_ip"])
{
$ip = $http_server_vars["http_client_ip"];
}
elseif ($http_server_vars["remote_addr"])
