Dependency Injection

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.

Very good job. 5 minutes to explain what other tutorials take over an hour.

[mrsoneji]

We need more language agnostic tutorials like this!

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.

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!

[darknawg]

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

I believe this is the BEST tutorial explaining this abstract concept in YOUTUBE. Thank you!!

Still shines like gold, 6 years later. Amazingly simple, to-the-point, succinct explanation.

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.

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 ^^

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.

[JSicking]

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!

[tcindie]

This may be the most clear and concise coverage of this topic I've ever encountered. You've earned my subscription :)

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...

10 years ago, but your guide is:
- short
- easy to understand
I am very grateful to you for that!

[danmo]

you know it's a timeless video when 10 years later I'm still watching it.

[Kralnor]

Thank you! This was the best explanation of Dependency Injection that I've seen so far.

[omkarpatil]

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!

[TheIronWaffleMan]

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.

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.
