How to create a PHP function library that supports dependency injection (DI): Create a Composer package as a function library. Implement function library functions, such as implementing a greeting function in a file. Install the PhpDI container and create a container configuration, adding the function library class to the container as a factory definition. Use libraries in code and inject dependencies, such as using containers to obtain instances of library classes. In practical applications, such as saving user data to the database, injecting database connections to improve flexibility.
