Question: In symfony framework service's is the same depedency injection ?

What is the difference beetwen service container as Dependency Injection ?

Answer: 
service container as Dependency Injection is a concept for applications developer. Each langugage paradigm as Java, Python or PHP has a service container (DI for Dependency Injection).

For the framework PHP Symfony it tells that Service Container (or just service). In DI concept you can easily delete the contain. It's a obviousness. Because all DI (Java, Python, etc...) live into a container or just a context.

If you already know language that Java and You want to know how symfony manage DI then I just says :"the service" in symfony is the concept of DI for this framework in PHP language.

You can read this post : [What is Dependency Injection](https://stackoverflow.com/questions/130794/what-is-dependency-injection)
There's pretty much a direct answer in the [Symfony docs](https://symfony.com/doc/current/components/dependency_injection.html):

> 
> The DependencyInjection component implements a PSR-11 compatible
>  service container that allows you to standardize and centralize the
>  way objects are constructed in your application.

Also, take a look at the [Service Container docs](https://symfony.com/doc/current/service_container.html).
