php 怎么实现前端统计流量

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 = Ƈ&#39; "; 
$queryset = mysql_query($querysql); 
$row = mysql_fetch_array($queryset); 
//获得时间量 
$DateNow = date(&#39;Y-m-d&#39;); 
$RecordDate = $row[&#39;RecordDate&#39;]; 
$DateNow_explode = explode("-",$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[&#39;CounterToday&#39;]; 
$upd_sql = "update mycounter set RecordDate = &#39;$RecordDate&#39;,CounterToday = &#39;$CounterToday&#39;,CounterLastDay = &#39;$CounterLastDay&#39; WHERE id = Ƈ&#39; "; 
mysql_query($upd_sql); 
} 
//再次获取数据 
$querysql = "SELECT * FROM `mycounter` WHERE id = Ƈ&#39; "; 
$queryset = mysql_query($querysql); 
$Counter = $row[&#39;Counter&#39;]; 
$CounterToday = $row[&#39;CounterToday&#39;]; 
$CounterLastDay = $row[&#39;CounterLastDay&#39;]; 
if($row = mysql_fetch_array($queryset) ){ 
if( $_COOKIE["user"] != "oldGuest" ){ 
$Counter = ++$row[&#39;Counter&#39;]; 
$CounterToday = ++$row[&#39;CounterToday&#39;]; 
$upd_sql = "update mycounter set counter = &#39;$Counter&#39;,CounterToday = &#39;$CounterToday&#39; WHERE id = Ƈ&#39; "; 
$myquery = mysql_query($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"); 
} 
?>
