1，用JS调用文件count.php
在需要加入统计的的地方，添加：
<script src="/php/count.php"></script>
2，php环境必须支持putenv()函数,可以统计昨日访问，今日访问，在线人数,您访问的次数。
3，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。
一，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 93 94 95 96 97 | <?/*** 统计IP及在线人数* edit www.jb200.com* date 2013/7/3*/$file = "count"; // 记数文件名称$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 = $t_array['year'];if (<a href="http://www.jb200.com/zt/file_exists/" target="_blank" class="infotextkey">file_exists</a>("$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;?> |
