DI Container With Interface Support - Full PHP 8 Tutorial 

This Tutorial is without any question the best Modern PHP Turorial on youtube now

Learning parts of Laravel even before Laravel course is fully out is the best!

By far the best channel I discovered recently. The stuff you teach and the way you teach. Thank you sir.

Thanks GIO! I got a job offer with your tutorials. I hope you always continue to train programming language becuase of your excellent teaching skills.

Haven't seen any better explanation. Great Tutorial.

So I've been able to write tests for the container class. I can't believe it. The lessons and the personal support have been amazing and even unbelievably unexpected. I'm very thankful Gio. God bless

Truly quadruple A quality content!

I worked with Laravel for over 3 years before I fully understood Service Containers. (Actually I didn’t care, I started looking into it about 2 years ago) Now the understanding keeps getting better. Thanks Gio ❤

Thank you! Thank you! Thank you! I've been building projects with Laravel for a while now and topics like this one always feels like a magic to me, something that i really don't understand, not until now. Now, reading the docs actually makes more sense now and much more interesting.

thank you gio for this awesome series

I am brazilian and your english is very good to understand, also great classes.

I've been stucking with the Laravel's container part and have no idea what it is used for. But after watching your videos, I think I'm getting to know what's going on. Thanks a lot for your tutorials and the hard work!

This advanced section is helping me dissect the Laravel framework Core. 😊

I get completely amazed watching your videos

Awesome tutorial ever I seen!!! Thx sit

My contribution for all the understanding you have given me on DI subject.

Thank you Gio

the best tutorial for modern php, great gio

Thank you for your effort, this is not easy to explain. The subject is really overwhelming. I want to check something. For example if I'm making new class and passing basic types in constructor like int, string etc, then I would not use container bc it will throw an error of invalid type. I presume than it's ok to make new object of that class somewhere down the road bc it has no further dependencies.

Looking forward to a video with how to use/mock the DI Container when testing!

Great video!

Amazing 🌟

Thanks for this lesson. Using Interfaces in DI makes a lot of sense. Thanks for teaching it. I've tried to go through the laravel repository and the laravel documentation. I'm only able to understand a percentage of the code and the documentation. I guess it now requires familiarity as I read more and use more. I'm hoping you atleast introduced laravel in the coming lessons cause I don't know much about it. Then the challenge to write some tests seem daunting... but I'll try it. Thanks and God bless

Thank you.

Good Work Thanks @Program With Gio

Hi bro, can you please make tutorials about SOLID and some other patterns but with easy examples. :D

thanks alot for the great Gio

It was really great but it is missing something like interfaces aliases, kind of symfony has meaning "ServiceInterface $service1", "ServiceInterface $service2", not that I complain, but I just struggle with this kind of a necessity in a current project :D. Apart of that the whole series is as somebody mentionned above the best one on php I've seen so far.

Being able to mock the service is another reason to use the interface instead of a concrete classs

@ProgrammingWithGio Hey Gio, Just started on the series and loving it so far. Thank you so much for your time and effort you put in on this. Are we going to work on an projects in this series for more hands on. If not, I'm cool with it I can start something small myself just if you have plans too then I'll wait because I have a long way to go to caught up anyway and it always helped me to see everything kind of come together.

waiting for laravel & vue or TALL stack content. much appreciated to your php series.

Very good level

Hey, thanks for this awesome tutorial mate. I'm confused where there are different dependencies with the same interface but how can I use them at the same time. For example: If I want to use both PaddlePayment and StripePayment for different purposes. How can I do this? I tried setting up containers for both but one would overwrite another. Btw, I'm using Yii2. :) Thanks, heaps!

Will you be making a series for larvel as well or any other framework or will be including larvel in this series

I believe you've already composer dump-autoload the whole project using psr-11 right? because I'm new to PSR and Dependency Injection and I really don't see where you use any include or require

i don't understand the principle of caching for a service container. Is that about some serialization?

Something I don't understand. If $entry = PaymentGatwayService::class which you say is a fully qualified class name, why isn't that callable?

Awsome!. but how woud you handle two or more classes sharing same interface?

Hi, what if we have multiple different implementations of some interface as dependencies? How would the container know which concrete class to resolve? My guess is that modifications have to made to container methods? Like storing all the implementations in array (entries array would have to be 2 dimensional array), and modifying get and set, so it would work with interfaces in a special way? Or i'm overcomplecating things?

Hi man, looking again and again at your videos. I have a question at 10:10, for example i have an API which process some transactions with different payment methods, how to avoid hard-code the payment like in your example, the PaddlePayment, let's say in your APP you have to use both methods, or many methods, the request should contain the method which we are going to use, and based on the name of the method we load the exactly Payment Class? like a factory pattern? Thanks for your videos man, i suggest to make some courses for udemy, or make your own buisness..you are great.

Hi Bro, sorry to fallback. I am trying to understand each line of code and learn. I have problem with the line "return $entry(this)". I do not understand that syntax. What does "$entry(this)" do? What does "this" refer to?

Hey Gio. Thanks for the tutorial. Could you please check my pull request where I implemented tests for Container class. Thank you in advance

05:30 if it works don’t touch it anymore…

Bro you better check your mail i send you someting!

it looks like laravel writers were cheating from us all this time 😂

now i can imagine how hard hardware language like java c++ c c# python or... I was completely confused when I saw these 2 videos i mean this and previous i've seen this 2 video 2 times but still a bit confusing for me your tutorial is underrated my iq is 101 which is not useful for programming at all :)programming requires at least an iq 130 you don't understand what i mean because you have high iq but finally with your tutorial i can write something like laravel routing and make tutorial with it for make money, and of course i see tutorial of c++ or c from basic to advanced these tutorials are even purchased for gaming modding hacking like trainer but I could not even make a button the reason is not my iq the reason is a bad tutorial because compared to your tutorial all of them is just beginner not even intermediate but can't support you on patreon maybe in the future if i alive and well , also spend almost $120 for web programming html css php that mean equal to $3300 now in country i living but all even tutorial is purchased they are not even half your intermediate tutorial i just want to say thank you i hope you could change the future programming tutorial and do not despair in this way because there are people who say wrong things out of jealousy i have instagram channel but I do not log in at all maybe for business because it's filter and I do not like this type of social network i just spend my time in youtube also youtube is filter but is use free vpn but also i have no subscriber i just can hit the like button and make playlist for your video i know doesn't effective but that's the only thing I can do

Bro, when you rename a file, e.g StripePayment, you are using PHPStorm which does the refactoring. This does not happen with VS Code and therefore we miss a number code change and things dont work.

Thank you, very interesting! Can you show middlewares principle?
