php是可以echo出来js代码的,有何不可
即使就是JS文件,它的后缀名也可以是.php或者其他的
根据你这个链接的情况来看,因为后面带了两个参数,很可能是根据参数的不同返回不同的JS文件,
还有一种可能是本来就是JS文件,不过伪造成PHP文件而已,具体可以参考.htaccess

Select 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.

Dependency injection (DI) significantly improves the testability of PHP code by explicitly transitive dependencies. 1) DI decoupling classes and specific implementations make testing and maintenance more flexible. 2) Among the three types, the constructor injects explicit expression dependencies to keep the state consistent. 3) Use DI containers to manage complex dependencies to improve code quality and development efficiency.
