1.用JS调用文件count.php 在你需要加入统计的的地方加入 实际运用中注意修改路径!
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相同目录建立以下文件 count,temp,online,新建文本文档count.txt 然后去掉扩展名就是文件count了;如果是Linux主机请把这三个文件属性设为777.
count.php文件代码:
$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
