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。

本文操作环境：Windows7系统，PHP7.1版，Dell G3电脑。

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 pubpc function ShowMyCounter(){ //定义变量 $IsGone = FALSE; //读取数据 $querysql = “SELECT * FROM `mycounter` WHERE id = Ƈ’ “; $queryset = mysql_query($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 = Ƈ’ “; mysql_query($upd_sql); } //再次获取数据 $querysql = “SELECT * FROM `mycounter` WHERE id = Ƈ’ “; $queryset = mysql_query($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 = Ƈ’ “; $myquery = mysql_query($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”); } ?>
