第一段yii2的代码,功能是检测用户是否创建当天日志。如果未创建,立即创建,并且保存。
为了避免大量查询数据库,所以保存到session中(可能不是很好?)。
欢迎指正其中的优缺点(逻辑是否正确):

免责声明,我没写过yii,只能从OOP的方向说一下问题
我觉得这个代码,依赖关系搞错了,这个逻辑上,应该是$app->user $app->session依赖record,而现在是record依赖user和session
所以如果我来封装,应该大概是这样
php
class MemberLog { public function __construct($user) { // find record by user $this->record = findByUser($user); } public function check() { $this->record->doSomething(); } }
