[UgoAugustoGustavoGuazelli]

The point using interfaces is you can make sure your class must have a method otherwise the class cannot be implemented.
Using the cat example, if you implement the the interface talk, you ensure your cat will talk, if you forget to create the method talk, the PHP error will remember you.
Note to the author : You should hold back on the speed.

"I should have mentioned that earlier" were his last words xD
As an experienced developer trying to refresh my php skills, i watch the videos at 1.25 times speed. Pretty good series!

I actually like videos being this short as sometimes tutorials can get tiring. This one goes straight to the point and anytime you don't get something you can pause and go back.

@Franklin Waller When using dependency injection and you want to call a method from the object that you injected, you may have to check if the method exists first. Interfaces eliminate that. If we inject an object that implements an interface, we *know* for certain that the method is present.

I just learned how a dog talks and what a cat says. Thanks!

You might want to hold back on the speed. For people that are new to OOP it's a lot of information to take in. Good tutorial besides that one thing.

People are complaining but this is the perfect tutorial !

This video is at an okay pace. However, what it may be missing is the difference between implementing an interface and extending a class, and why you would use one and not the other.

Everyone is talking about how fast he is going, while i'm here watching this with 1.5x speed D:

Truly awesome work! Thank you... Just wondering if you could do a series on WordPress REST API + VueJS + SPA ? No one is doing this yet but I can promise you this will catch on like wildfire. Almost 30% of the web is sitting on WordPress and growing ... cheers!!

Great video, but isnt the end of the video missing? it just stops

[FirstLast-rmmb]

Series was looking to be excellent until 6/13. Do you have any other vids on these topics?

[Shifter]

Too fast .. i can't understand anything !!!

[ThaRSGeek]

Still a little blurry for me why to use this...

[raphaelandrade]

Why should I implement this interface if I can make my own function "count2"??? :/

[TomSmith]

Franklin if you wanted to create an API this would be important.

[sandarabian]

does "this->items[] = $value" have the same effect as "this->items[]->push($value)" ?

[zamzung]

Why do you use echo json_encode($c) instead of echo $c->jsonSerialize(); . We implemented method, and then we don't call it ?.
Is method jsonSerialize() some how called with with json_encode function ? I don't get it

[MrFrimko]

stop start ever 1.5 second... please a little bit slower in future, its annoying
good information but hard to recieve, couse super fast

[cjvaans]

My goodness. I couldn't understand anything. He lectures too fast.
