$model1 = M('baby');
$user_data['user_name'] = $username;
$user_data['password'] = $password;
$user_data['createtime'] = time();
$user_data['lastupdate'] = time();
$model2 = new Model("user","","mysql://www:123456@localhost:3306/test");
$model2->add($user_data);这样不能实现切换数据库，只有把$model1去掉才行，请问这是什么原因？ 最佳答案
