本文实例讲述了PHP简单实现记录网站访问量功能。分享给大家供大家参考,具体如下:

tongji/index.php文件:

$file = dirname(__FILE__).'/tongji.db';
//$data = unserialize(file_get_contents($file));
$fp=fopen($file,'r+');
$content='';
if (flock($fp,LOCK_EX)){
while (($buffer=fgets($fp,1024))!=false){
$content=$content.$buffer;
}
$data=unserialize($content);
//设置记录键值
$total = 'total';
$month = date('Ym');
$today = date('Ymd');
$yesterday = date('Ymd',strtotime("-1 day"));
$tongji = array();
// 总访问增加
$tongji[$total] = $data[$total] + 1;
// 本月访问量增加
$tongji[$month] = $data[$month] + 1;
// 今日访问增加
$tongji[$today] = $data[$today] + 1;
//保持昨天访问
$tongji[$yesterday] = $data[$yesterday];
//保存统计数据
ftruncate($fp,0); // 将文件截断到给定的长度
rewind($fp); // 倒回文件指针的位置
fwrite($fp, serialize($tongji));
flock($fp,LOCK_UN);
fclose($fp);
//输出数据
$total = $tongji[$total];
$month = $tongji[$month];
$today = $tongji[$today];
$yesterday = $tongji[$yesterday]?$tongji[$yesterday]:0;
echo "document.write('访总问 {$total}, 本月 {$month}, 昨日 {$yesterday}, 今日 {$today}');";
}


使用方法(通过js引入tongji/index.php文件):
