① php流量统计功能的实现代码
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
本代码仅供学习交流，其中必有不妥之处。请见谅！

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
=
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：".$CounterLastDay;
}else{//如果数据库为空时，相应的操作
}
}
?>
当然，需要在文件第一行开始写出如下代码：
复制代码
代码如下:
<?PHP
session_start();
if(
!isset($_COOKIE["user"])
){
setcookie("user","newGuest",time()+3600);
}else
{
setcookie("user","oldGuest");
}
?>
