写在前面的话

很多人有这样的需求,就是统计网站访问IP以及在线的人数。今天我们就看一下具体实现方法。

开启依赖函数模块

实现这个功能,需要依赖putenv()函数。下面两种方式均可。

更改php.ini文件方法

找到php.ini文件,搜索putenv关键字,删除即可。

isable_functions = passthru,exec,system,putenv,chroot,chgrp,chown,shell_exec,popen,proc_open,pcntl_exec,ini_alter,ini_restore,dl,openlog,syslog,readlink,symlink,popepassthru,pcntl_alarm,pcntl_fork,pcntl_waitpid,pcntl_wait,pcntl_wifexited,pcntl_wifstopped,pcntl_wifsignaled,pcntl_wifcontinued,pcntl_wexitstatus,pcntl_wtermsig,pcntl_wstopsig,pcntl_signal,pcntl_signal_dispatch,pcntl_get_last_error,pcntl_strerror,pcntl_sigprocmask,pcntl_sigwaitinfo,pcntl_sigtimedwait,pcntl_exec,pcntl_getpriority,pcntl_setpriority,imap_open,apache_setenv

使用宝塔面板

点击左侧软件管理,找到php,然后设置->禁用函数。

删除putenv,然后重启php即可。

实现函数

在count.php同目录下创建文件:count,temp,online。新建文本文档count.txt,去掉扩展名即为count了;

linux系统中请设置文件属性为:777。

文件count.php代码,用到了php函数--explode、isset、empty及sprintf等:

<?php
$file       = "count"; // 记数文件名称
$startno     = "1000";  // 起始数值
$tempfile     = "temp"; 
$t_now  = time();
$t_array = getdate($t_now);
$day   = $t_array['mday'];
$mon   = $t_array['mon'];
$year  = $t_array['year'];
if (file_exists("$file")) {
    $count_info=file("$file");
    $c_info = explode(",", $count_info[0]);
    $total_c=$c_info[0];
    $yesterday_c=$c_info[1];
    $today_c=$c_info[2];
    $lastday=$c_info[3];
} else {
    $total_c="$startno";
    $yesterday_c="0";
    $today_c="0";
    $lastday="0";
}
 
if ( !isset($HTTP_COOKIE_VARS["countcookie"]) || $HTTP_COOKIE_VARS["countcookie"] != $day) {
    $your_c=1;
    $lockfile=fopen("temp","a");
    flock($lockfile,3);
    putenv('TZ=JST-9');
 
    $t_array2 = getdate($t_now-24*3600);
    $day2=$t_array2['mday'];
    $mon2=$t_array2['mon'];
    $year2=$t_array2['year'];
    $today = "$year-$mon-$day";
    $yesterday = "$year2-$mon2-$day2";
    if ($today != $lastday) {
  
           if ($yesterday != $lastday) $yesterday_c = "0";
               else $yesterday_c = $today_c;
  
        $today_c = 0;
        $lastday = $today;
    }
    $total_c++;
    $today_c++;
    $total_c   = sprintf("%06d", $total_c);
    $today_c   = sprintf("%06d", $today_c);
    $yesterday_c = sprintf("%06d", $yesterday_c);
    setcookie("countcookie","$day",$t_now+43200);
    $fp=fopen("$file","w");
    fputs($fp, "$total_c,$yesterday_c,$today_c,$lastday");
    fclose($fp);
    fclose($lockfile);
}
if ( empty( $your_c ) ) $your_c = 1;
setcookie("yourcount",$your_c+1,$t_now+43200);
$your_c = sprintf("%06d", $your_c);
//////////////////////////开始统计在线
$filename="online";
$onlinetime=600; //同一IP在线时间,单位:秒
$online_id=file($filename);
$total_online=count($online_id);
$ip=getenv("REMOTE_ADDR");
$nowtime=time();
 for($i=0;$i<$total_online;$i++){
     $oldip=explode("||",$online_id[$i]);
     $hasonlinetime=$nowtime-$oldip[0];
 if($hasonlinetime<$onlinetime and $ip!=$oldip[1]) $nowonline[]=$online_id[$i];
                 }
     $nowonline[]=$nowtime."||".$ip."||";
     $total_online=count($nowonline);
     $fp=fopen($filename,"w");
     rewind($fp);
     for($i=0;$i<$total_online;$i++){
     fputs($fp,$nowonline[$i]);
     fputs($fp,"n");
                 }
 fclose($fp);
   if($total_online==0)$total_online=1;
        $total_online = sprintf("%06d", $total_online);
///////////////////////////////////////////////////////
echo "document.write("·总IP访问:".$total_c."");";
echo "document.write("<br>");";
echo "document.write("·昨日访问:".$yesterday_c."");";
echo "document.write("<br>");";
echo "document.write("今日IP:".$today_c."");";
echo "document.write("");";
echo "document.write("·您 访 问:".$your_c."");";
echo "document.write("<br>");";
echo "document.write("当前在线:".$total_online."");";
exit;
?>

调用

用JS调用文件count.php

在需要加入统计的的地方,添加:

<script src="https://www.atool.online/php/count.php"></script>
