php在线预览word/rtf/pdf文件
小弟初学php,现要实现一个功能,将用户上传的word/rtf/pdf文件在线预览/显示出来。类似于owa(outlook web access)里面的预览word/excel/ppt等附件的功能。
请有经验的朋友指教一二,万分感激。

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.
