Dependency Injection
Ғылым және технология
This week, we're going to talk about the topic of Dependency Injection in Object oriented code (specifically PHP). You don't need a fancy container to do it, it's actually quite simple to do manually!

8 years ago you uploaded this 5 minutes video that has helped me understand this concept that I didn't understand by watching videos and reading articles uploaded and written in 2021 respectively. Thank you mate.

It IS good... but not quite sufficient. It leaves one with the impression that DI is like a singleton with lazy init'ing getters.

Unfortunately his explanation is full of mistakes. He explains what he thinks DI is about and not what it actually is defined to be. Thumbs down. I think, he knows better, but really explains an abstruction of what DI is for the "dummy" youtube user. If this was the case, he probably did a good job.
We need more language agnostic tutorials like this!

This is absolutely fantastic. Brilliantly explained. Went from being iffy on the concept to totally getting it (at least as far as the video explains). Great job.
These 5 minutes have been the most productive minutes of my life. I have seen so many videos and have read about dependency injection, but no one has explained it so well. Thank you Anthony Ferrera. Keep up your good work.
I believe this is the BEST tutorial explaining this abstract concept in KZread. Thank you!!
Now thats what I call a real tutorial...clear concise and hit the nail on the head....looking forward to many such tutorials from you Sir.
Holy crap this is one of the simplest most straightforward explanations for something I've spent a real long time trying to totally wrap my head around. Awesome job and thanks!
This may be the most clear and concise coverage of this topic I've ever encountered. You've earned my subscription :)
Others have already said it but this is definitely the best explanation on KZread. Your video on mediators was great too. I really hope you make more of these videos about design patterns and programming concepts.
5 minutes of clear explanation ...there is a plethora of explanations of DI out there that cloud over (obfuscate) the very simple and central themes of DI...this video is straight to the point...Thanks Anthony...
very well done. I like how he basically explained dependency inversion in the same tutorial. was struggling with both concepts. now both are crystal clear.
Awesome! I read, watched, searched for a lot of stuff to understand what's Dependy Injection and how and why to use it. In this f** simple video, you explained everything! Thank you!
you know it's a timeless video when 10 years later I'm still watching it.
Out of the dozen videos I've watched and multiple books I've read through, this was hands down the best explanation of DI I've come across. Even while framework/language agnostic no less. Thank you.
I watched several videos explaining this and this was the most direct, clear, and shortest video. Well done 👍
Thank you for taking the time to put this together and sharing. Its amazing what you can get out of 5 (well done) minutes. Very helpful!
OMG! I finally get it. This is the clearest explaination that I've ever heard on DI. Proof that the teacher makes all of the difference. Thanks you Anthony. +1
this is just the best DI explanation i've ever seen !
I come back to this video so much, it's literally the best explanation of dependency injection.
This is the BEST explination i have ever seen since i started learning programing, such a great way to explain the logic which most of us struggle with :)
Perfectly clear and simple for all languages that use DI. This isn't even for Java and 100 times better than Java DI videos ... Bravo!
THANK YOU, for this! I've seen like 5 videos before this, but yours was the shortest, cleanest and I can finally say I understand the principle after watching it!
Man! This is the best explanation I have ever heard on dependency injection. Amazing.
This is the best explanation for DI I have come across.
Still shines like gold, 6 years later. Amazingly simple, to-the-point, succinct explanation.
looking for a simple explanation about the topic, and found this 7 years old video is actually the best one that I've found.. thank you.
I've been struggling to understand DI for while. This was so clear and understandable. Thank you good sir!
These last couple of days I've been looking into dependency injection quite a bit: how to do it, why to do it etc. etc, and while I understood what was being said, I didn't have a clue how it all fit together. You explained the workflow clearly and concisely, and it made all the pieces fall into place! Thank you very much ^^
10 years ago, but your guide is: - short - easy to understand I am very grateful to you for that!
Thank you! This was the best explanation of Dependency Injection that I've seen so far.
I love your screencasts! You do such a good job of explaining new/complex concepts. Please keep doing them!
Thanks, it took me just 5 min to fully understand DI with your explaination, very clear.
Thank you for taking out time to make this video all those years ago. Much appreciated toay.
I saw the video in the library, without headphones, just with the subtitles... even then was perfectly explained, thanks a lot!
Brilliantly explained! Its all because your concepts are so clear ....
Anthony, this is brilliant. Very succinct and at the same time clear and easy to visualize and follow thanks to you writing and drawings.
best explanation I have ever heard. Clear and concise.
Wow I am amazed by this video, such an elegant explanation! The best tutorial on dependency injection by far
I appreciate the unique format used in presenting information in this video.
After exactly 10 years, thank you!
wow.... I would say old but gold for this video. straight to the point, very clear and it's just 5 min. Thank you
The way you explained it by the example is marvelous. Only by this video I understood dependency injection.
Best explanation of Dependency Injection I've ever seen.
This is the best tutorial I've ever found about this topic. To put in practice I recommend laracast's The PHP Practitioner free course. PS.: Just figured out that ircmaxell is your blog, man. I already read some posts that are really great, thanks for sharing your knowledge. You are a really good teacher.
Very well done. Great explanation and clear delivery. Can't wait to see more.
Jesus Christ other tutorials take so long to get to the concept, but this one was short and sweet! Thank you very much
Thanks, by far the best explanation about DI and its usage. Thanks!!
Your videos are so great to understand complex things. Please keep going. Thanks for your work.
this is the best tutorial about dependency injection! Extremely easy to understand!
Anthony, loved your video. It's clear, quick and to the point.10X!
That's the best explanation for Dependency Injection I've heard so far. I can implement it and know why I should do so, but "Dependancy Injection" remained a foreign word to me, until I saw this video and it clicked.
Thanks man. People like you make the world go round.
Wow, i'm only beginning to learn how to code and this video just broke what was an unreachable concept for my mind into something that was so understandable. Thank you sir!
Simple and concise... Thanks very much for your time explaining this!
You made me believe of the power of briefly 💪 please keep doing all the up coming videos just like that. Awesome 👏
I'll have an interview soon and this is the best video I could find about DI.
Upon further reflection, this is the best and most succinct explanation of DI.
wow..i have watched many videos before related to CI. this is the best out of best.great stuff Anthony..You are truly a master of explaining complex stuff in a simpler manner. Keep it up.Well done and thank you very much. :)
8 years later... and this video is as relevant today as it was when it was uploaded!
Really awsome , it takes 5 min to understand what other tutorial take hours, very good job, and thank you
THANK YOU for finally explaining this in a simple matter. Once again your videos have helped me.
Amazing! Love your explanation, with pictures!!
seriously this is gold explanation ! salute

Thank you for this video. I like your presentation style. Great way to explain concepts, and makes it more concrete in terms of understanding how it is applied in code.
Brilliantly explained! Really love your teaching style
don't leave us Anthony, you are a great asset for the php community, great videos
That was a very clean explanation of a rather seemingly complex concept. Thanks for putting this up :)
Wow best explanation so far!
I subscribed because of this video. Straight to the point
Your video was very helpful. It explained DI in a straight-forward, interesting way.
I don't know how to thank you for this fantastic tutorial. So easy to understand so interesting....
Awesome work 🙂 Clear and concise.
Very well explained! The "wall-building robot" example was excellent in explaining decoupling!

The paradigm of decoupling was not explained by the robot door example nor by other video parts. You could use inheritance or just initiate a new object from the supplier to achieve the goal. A viewer still cannot explain why to use DI to really have it decoupled nor what decoupling really means. I know it :) do you?

Thanks It's clear you have a very deep understanding of the subject in order to make such a concise video. Kudos!
Very illustrative, easy to follow and understand.
This was a great video, perfect for the visual learner like myself. The drawings helped alot.
I've always read about this in various articles, but it always comes across as a bunch of words trying to explain something to me, but relies on further reading of other related principles which ultimately just makes it more confusing. Sure it's good for the SEO of your website but it just doesn't help someone who just needs a simple answer. Luckily, I found this video. Straight to the point with a really easy-to-understand analogy.
Wonderful!!!! The wall-building robot was genius!
Amazing! Great timbre, information and visualization.
How is this guy not popular on the YT programming scene. If you're reading this... put out more videos dude, SO HELPFUL!
Thank you! That's the best explanation I've ever got.
a great explanation of dependency injection i have viewed in my life.
A really excellent and simple explanation of DI. Wish I had this when I started using DI over 2 years ago, non the less always a good idea to revise knowledge.
This was so simple short and well explained
Great job, simple explanation, also liked very much the format you used for your video. Keep up the good work!
Simple ,Clear , Useful Explation
Uploaded 7 years back but it was neat explanation. Thanks mate :)
Brief and clear explanation. Thanks a lot!
I will thank you for this great explanation but also for being the first programmer to have a readable handwriting.
Excellent explanation. loved it. Thank you.
Thank you! So easy and so understandable material!
THANK YOU! This is a perfect explanation. I might show it in my programming classes!
