增加一个selectdatabase的操作不行吗?
例子
<code>class Db{ function selectDb($dbname,$link){ mysql_select_db($dbname, $link); } function link($host,$user,$pass){ $link=mysql_connect($host,$user,$pass); return $link; } function query(...){...} .... } </code>
你在类中创建,看看能不能行
使用的时候只需要试用一下selectdb
使用方法 类似
$db=new Db; $link=$db->link(......); $db->selectdb('admin'); $result=$db->query('select * frome admin');
我这举了个可行性的例子,具体的可以参照现成的数据库类进行相应修改。
