php在线人数据统计程序源码

这种一款可以统计你网站当前在线人数的代码,由php+txt实现的无需数据来来支持,PHP+txt实例代码如下:

<?php
$time = gettimeofday(void);
//文件初始化 start
if (@filesize("time.text") <= 0) {
    $fd_time = fopen("time.text", "w+");
    fputs($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"]) {
    $ip = $http_server_vars["remote_addr"];
} elseif (getenv("http_x_forwarded_for")) {
    $ip = getenv("http_x_forwarded_for");
} elseif (getenv("http_client_ip")) {
    $ip = getenv("http_client_ip");
} elseif (getenv("remote_addr")) {
    $ip = getenv("remote_addr");
} else {
    $ip = "unknown";
}
$ip_adds = file("ip.text");
for ($i; $i < count($ip_adds); $i++) {
    if ($ip . " " == $ip_adds[$i]) {
        $ip_check = 1;
        break;
    }
}
if ($ip_check != 1) {
    fputs($fd_ip, $ip . " ");
}
fclose($fd_ip);
//检查ip over
$ip_adds = count(file("ip.text"));
?>

调用方法:

<?php
/*
 * 标题：简单在线人数统计
 *
 * 作者：邓东东
 *
 **/
include ("online.php");
$fd_ip = file("ip.text");
?>
<title>在线人数</title> 
<center><font color=blue size=6>php100论坛在线总人数为:<font color=red size=8><?php echo $ip_adds08610071 < / font > 人 < br > 用户ip： < ? phpecho "<select>";
for ($i = 0; $i < count($ip_adds); $i++) {
    echo "<option value = &#39;$i&#39;>" . substr($fd_ip[$i], 0, 0 - strlen(strrchr($fd_ip[$i], &#39;.&#39;))) . ".*</option> ";
}
echo "</select>";
?>
</font></center>
