最近公司用了YII框架，但是关于夸应用调用模型会出现问题，情况是这样的：
应用1的模型数据库连的是db1
应用2的模型数据库连的是db2
那么在 应用1中调用db2会发现坑爹的是连的db1的表，虽然调用的的的确确是db2的类，有熟悉YII的么？求指点，想要快应用调用model^ ^
回复讨论(解决方案)
你的做法是有问题的
既然应用1和应用2是两个独立的项目，那么这两个项目间就不应该发生代码层面的联系
如果应用1需要利用应用2的结果，那应该通过rest或api方式进行
如果应用1只是需要利用应用2的算法，那么应复制相关代码过来
当然也可以 include，但这样话耦合也太紧了吧
嗯，的确是耦合性的问题，已经知道问题所在了，因为数据库连接是单例模式，那么只要$db变量不为空那么就直接返回，所以，当连接另一库的时候因为$db不为空，那么直接返回，那么此时$db还是前一个数据库的连接，thank you!
