Benefits of php dependency injection

My view on DI (Dependency Injection) has always been that it is more about dependency management than dependency injection. In fact, it is somewhat similar to a higher level such as composer, pip, and maven. Tools for managing dependencies between applications and libraries. The DI framework will bring these benefits (prerequisite is a good DI framework): (Recommended learning: PHP Video Tutorial)

Change the implementation of the dependent interface through configuration, which is also the most basic and core function of the DI function

Flexibly control the instance scope of the dependent implementation, singleton, one for each thread, and each Each request and so on

Dependent parameters, dependent dependencies, etc. management

Good DI framework:

Laravel is a simple and elegant PHP Web Development Framework (PHP Web Framework ).

It can free you from messy codes like noodles; it can help you build a perfect network APP, and every line of code can be concise and expressive.

Laravel already has an advanced PHP ActiveRecord implementation -- Eloquent ORM. It can easily apply "constraints" to both sides of the relationship, so that you have complete control over the data and enjoy all the conveniences of ActiveRecord. Eloquent natively supports all methods of the query builder (query-builder) in Fluent.

High Quality Documentation

Laravel has a great community support. The expressiveness and good documentation of the Laravel code itself make PHP programming a pleasure.

Rich expansion packages

Bundle is the name for expansion packages in Laravel. It can be anything - as large as a complete ORM, as small as a debug tool, or just copy & paste to install any extension! Laravel's extension packs are contributed by developers from all over the world, and more are constantly being added.

Open source, hosted on GITHUB

Laravel is completely open source. All code is available on Github, and you are welcome to contribute.
