当我在具有新域的另一个托管服务器上转移站点时,出现此PHP错误.我已经正确更改了所有数据库设置.我是Yii的新手,不确定如何正确设置.有人说这是PDO的问题,但我不太确定.
我们如何解决这个问题？

解决方法:
听起来您没有在服务器上启用PHP PDO扩展：
http://php.net/manual/en/book.pdo.php
Yii附带了requirement checker script,您可以用来确保新主机满足Yii要求(在Yii库目录中的requirements目录中).该URL将是这样的：
http://hostname/path/to/yii/requirements/index.php
