我想做这样的事情

Select * from users where id = $user_id
但我如何才能在YII中实现这一点

这就是我正在尝试的

$user = Yii::app->db->createCommand('SELECT * FROM users where user_id = "$user_id"')->queryAll();
返回一个空数组

您可以使用bindValue

 $user = Yii::app->db->createCommand('SELECT * FROM users where user_id = :user_id')
        ->bindValue(':user_id',  $user_id)
        ->queryAll();
