-- 表的结构 `mycounter`
--

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:

代码如下:

<?PHP 
public 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] ) $IsGone = TRUE; 
}else BREAK; 
}else BREAK; 
//根据IsGone进行相应操作 
IF($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:

代码如下:

<?PHP 
session_start(); 
if( !isset($_COOKIE["user"]) ){ 
setcookie("user","newGuest",time()+3600); 
}else { 
setcookie("user","oldGuest"); 
} 
?>
