Yii 2.0.13 已经修复此问题了，原先继承 yii\base\Object 的话，现在改成继承 yii\base\BaseObject

更新日志链接：http://www.yiiframework.com/news/149/yii-2-0-13-is-released/ 中的 PHP 7.2 compatibility

from(db.table)

可以这样:

var $username='张三';
var $email ='qq@qq.com';
var $mobile =18888888888;

$result=User::find()->where([
'status'=>1,
])->andwhere([
'or',
['like','username',$username],
['like','email',$email],
['like','mobile',$mobile],
])->all();

可以使用sweet-alert

$sql = $queryBuilder->batchInsert('user', ['name', 'age'], [
    ['Tom', 30],
    ['Jane', 20],
    ['Linda', 25],
]);
