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!

Dependency Injection in PHP: Code Examples for BeginnersMay 14, 2025 am 12:08 AMYou should care about DependencyInjection(DI) because it makes your code clearer and easier to maintain. 1) DI makes it more modular by decoupling classes, 2) improves the convenience of testing and code flexibility, 3) Use DI containers to manage complex dependencies, but pay attention to performance impact and circular dependencies, 4) The best practice is to rely on abstract interfaces to achieve loose coupling.

Dependency Injection vs. Service Locator in PHPMay 13, 2025 am 12:10 AMSelect DependencyInjection (DI) for large applications, ServiceLocator is suitable for small projects or prototypes. 1) DI improves the testability and modularity of the code through constructor injection. 2) ServiceLocator obtains services through center registration, which is convenient but may lead to an increase in code coupling.

mPDF
mPDF is a PHP library that can generate PDF files from UTF-8 encoded HTML. The original author, Ian Back, wrote mPDF to output PDF files "on the fly" from his website and handle different languages. It is slower than original scripts like HTML2FPDF and produces larger files when using Unicode fonts, but supports CSS styles etc. and has a lot of enhancements. Supports almost all languages, including RTL (Arabic and Hebrew) and CJK (Chinese, Japanese and Korean). Supports nested block-level elements (such as P, DIV),
