按照如下步骤出错：
代码： 全选
if($_SERVER["HTTP_HOST"]=="A域名.com" || $_SERVER["HTTP_HOST"]=="www.A域名.com"){
$db = new Typecho_Db('Mysql', 'A_');
}
else if($_SERVER["HTTP_HOST"]=="B域名.com" || $_SERVER["HTTP_HOST"]=="www.B域名.com"){
$db = new Typecho_Db('Mysql', 'B_');
}
$db->addServer(array (
'host' => 'localhost',
'user' => '数据库用户名',
'password' => '数据库密码',
'charset' => 'utf8',
'port' => '3306',
'database' => '数据库名',
), Typecho_Db::READ | Typecho_Db::WRITE);
Typecho_Db::set($db);
两个网站都可以I正常运行，网站提示：
