-- 表的结构 `mycounter`

--

复制代码 代码如下:

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：

复制代码 代码如下:

<?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;

}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：

复制代码 代码如下:

<?PHP

session_start();

if( !isset($_COOKIE["user"]) ){

setcookie("user","newGuest",time()+3600);

}else {

setcookie("user","oldGuest");

}

?>
