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>
