关于php：我可以使用这个数据库package器类来连接两个以上的数据库吗

Can i use this database wrapper class for connecting more than two databases

我正在使用此数据库package器类http://www.ajaxray.com/blog/2009/08/29/simple-php-pdo-wrapper-light-static-easy-to-use//

我可以使用此数据库package器类从一个数据库中获取数据并插入到另一个数据库中吗。

如果是，那么我应该如何使用它？

例如我想执行以下查询。

1
2
3
4
5
6
7
8
9
10
11
12
13
14
15
16

echo $select_resellerData ="select * from resellerDetailsEntry where date_format(updatedon,'%Y-%m-%d')='".$date_var.str_pad($i, 2,"0", STR_PAD_LEFT)."'";

$fetch = querytobeexecutedfrom_A_Db($select_resellerData);

while($row_reseller = mysql_fetch_array($fetch))
{
//echo $row_reseller['alloctype'];
##-------------------------------------------Insert into reseller dashboard for each reseller-------------------------------##
$insert_into ="insert into tbl_reseller_dashboard_intermediate set
firstname ='".$row_reseller['firstname']."',
lastname ='".$row_reseller['lastname']."',
mobile ='".$row_reseller['mobile']."',
email ='".$row_reseller['email']."',
citybelongsto ='".$row_reseller['citybelongsto']."',
cityoptedfor ='".$row_reseller['cityoptedfor']."',
tmecode ='".$row_reseller['tmecode']."',
tmename ='".$row_reseller['tmename']."',
updatedon ='".$row_reseller['updatedon']."',
apptype ='".$row_reseller['apptype']."',
empparent='".$row_reseller['data_city']."',

entrydate ='".$date_var.str_pad($i, 2,"0", STR_PAD_LEFT)."'";

$run=querytobeexecutedfrom_B_Db($insert_into);
}

如何使用此数据库package器类执行querytobeexecutefrom_A_Db和querytobeexecutefrom_B_Db？
