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:

1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 29 30 31 32 33 34 35 36 37 38 39 40 41 42 43 44 45 46 47 48 49 50 51 52 53 54 55 56 57 58 59 60 61 62 63 64 65 66 67 68 69 70 71 72 73 74 75 76 77 78 79 80 81 82 83 84 85 86 87 88 89 90 91 92 <?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 .
