yii2.0使用AR查询，将数据库时间戳格式化，如何在find()后将时间戳转换成日期格式

1.首先头部引入

use yii\db\Expression;

2.使用函数new Expression(）此示例中mysql处理时间戳函数from_unixtime

public static function getCashlog($data){
$log = MemberCashLog::find()->select(new Expression("from_unixtime(addtime,'%Y-%m-%d %H:%i') as add_time"))->where(['app_id'=>$data['app_id'],'memberid'=>$data['mid']])->asArray()->all();
return $log;
}
