php实现前端统计流量的方法：1、创建一个PHP示例文件；2、定义变量；3、读取数据；4、判断是否已过去一天；5、根据IsGone进行相应操作即可。

php 怎么实现前端统计流量？
php流量统计功能的实现代码
用php实现的流量统计功能代码，本代码仅供学习交流，其中必有不妥之处。
流量统计功能
显示效果：
总访问量：399 今日流量：14 昨日流量：16– — 表的结构 `mycounter` — CREATE TABLE `mycounter` ( `id` int(11) NOT NULL auto_increment, `Counter` int(11) NOT NULL, `CounterLastDay` int(10) default NULL, `CounterToday` int(10) default NULL, `RecordDate` date NOT NULL, PRIMARY KEY (`id`) ) ENGINE=InnoDB DEFAULT CHARSET=gbk AUTO_INCREMENT=2 ;
函数过程如下：
<?PHP public function ShowMyCounter(){ //定义变量 $IsGone = FALSE; //读取数据 $querysql = \”SELECT * FROM `mycounter` WHERE id = ?\’ \”; $queryset = mysql_query($querysql); $row = mysql_fetch_array($queryset); //获得时间量 $DateNow = date(\’Y-m-d\’); $RecordDate = $row[\’RecordDate\’]; $DateNow_explode = explode(\”-\”,$DateNow); $RecordDate_explode = explode(\”-\”,$RecordDate); //判断是否已过去一天 if( $DateNow_explode[0] > $RecordDate_explode[0]) $IsGone = TRUE; else if( $DateNow_explode[0] == $RecordDate_explode[0] ){ if( $DateNow_explode[1] > $RecordDate_explode[1] ) $IsGone = TRUE; else if( $DateNow_explode[1] == $RecordDate_explode[1] ){ if( $DateNow_explode[2] > $RecordDate_explode[2] ) $IsGone = TRUE; }else BREAK; // www.jbxue.com}else BREAK; //根据IsGone进行相应操作 IF($IsGone) { $RecordDate = $DateNow; $CounterToday = 0; $CounterLastDay = $row[\’CounterToday\’]; $upd_sql = \”update mycounter set RecordDate = \’$RecordDate\’,CounterToday = \’$CounterToday\’,CounterLastDay = \’$CounterLastDay\’ WHERE id = ?\’ \”; mysql_query($upd_sql); } //再次获取数据 $querysql = \”SELECT * FROM `mycounter` WHERE id = ?\’ \”; $queryset = mysql_query($querysql); $Counter = $row[\’Counter\’]; $CounterToday = $row[\’CounterToday\’]; $CounterLastDay = $row[\’CounterLastDay\’]; if($row = mysql_fetch_array($queryset) ){ if( $_COOKIE[\”user\”] != \”oldGuest\” ){ $Counter = $row[\’Counter\’]; $CounterToday = $row[\’CounterToday\’]; $upd_sql = \”update mycounter set counter = \’$Counter\’,CounterToday = \’$CounterToday\’ WHERE id = ?\’ \”; $myquery = mysql_query($upd_sql); } echo \”总访问量：\”.$Counter; echo \” \”; echo \”今日流量：\”.$CounterToday; echo \” \”; echo \”昨日流量：\”.$CounterLastDay; }else{//如果数据库为空时，相应的操作 } } ?>
当然，需要在文件第一行开始写出如下代码：
<?PHP session_start(); if( !isset($_COOKIE[\”user\”]) ){ setcookie(\”user\”,\”newGuest\”,time() 3600); }else { setcookie(\”user\”,\”oldGuest\”); } ?>
