Hi,

there is a problem with the last challenge...you can't finish the 3rd course because it does redirect you to https://symfonycasts.com/sc... after you finish.

Hey g0spon

That's a bit odd. It's working fine for me. What happens if you go to the main page of the course and then click directly on the challenge you need to accomplish? (in the chapters list)
https://symfonycasts.com/sc...

Cheers!

Hi, sorry for the late reply. I didn't explain the problem well. I watched all chapters and did all challenges right, but after the last challenge in chapter 10 after I finish and press "Finish the Course" it redirects me to the course 4 without course 3 badge and certificate. When I go to course 3 is says 93% complete even all challenges are green and i watched all videos. I'm obviously missing something.

g0spon I was wrong. I was checking episode by episode and realised that video for chapter 8 and 9 had no tick, probably i skiped videos before the end. Now it's all right. Sorry for bothering you.

Awesome course, the best I've seen of PHP OOP. I don't know if it would be possible to do similar with Javascript with ES7

Hey Jose carlos C.!

Woohoo! Glad you loved it - thanks for the super nice note :).

About the JavaScript & ES7 stuff... I think (hope) that we've already done it - https://symfonycasts.com/tr... - specifically the second tutorial - https://symfonycasts.com/sc.... There's actually not a TON of new features in ES7 and ES8 - so the ES6 tutorial is really the big, important stuff (then you can quickly google ES7 and ES8 to learn about a few nice, handy new functions).

I hope that's what you're looking for. Because, honestly, I LOVE that entire series :).

Cheers!

This is a fantastic course about OO, as an old procedural PHP developer, even if I've touched Symfony, and OO, I find a lot a good things and practices in here !
Simple question : In ShipStorageInterface, we define the return type in the PHPDoc for the fetchSingleShipData as "array()". What does the parenthesis mean exactly ?

Hey abyssweb

Thanks for your kind words, we love to hear that our tutorials are useful and fun for our users :)

About the extra parenthesis, nice catch! Actually they are not needed, I believe it came from the habit of defining empty arrays

Cheers!

Hey Matt!

Ah, awesome! Thanks for the nice words and dropping the real-world example! When you start thinking like this, then yea, you've definitely "grasped" the purpose of interfaces :)

Cheers!
