This tutorial uses Symfony 3, but all the concepts around PHP 7 are still ?valid.

What PHP libraries does this tutorial use?

    }
}

PHP 5 is dead! So it's finally time to look at PHP 7 and learn all about the important stuff it brings. We're talking about scalar type declarations, return types, and the spaceship operator! Actually, not that last thing - there is a new spaceship operator (<=>) in PHP 7, but other than having a cool name... it's not really very important. Instead, we'll focus on:

Scalar type declarations and return types
Nullable types
Void types
Class constant visibility
New error and exception handling

And, PHP7 is fast! So let's get to it!

Hi guys, do you plan to do a php 8 tutorial with the upcoming SF6 release (which will support php8 at least) ?

Hey Lionel F.!

Hmm, I honestly hadn't thought about it much yet, but that's a pretty good idea - a quick PHP 8 bootcamp people could use as they start using Symfony 6. Perhaps also with 8.1 features on top if it (Symfony 6 will only require 8.0, but 8.1 will release nearly the same day).

We'll talk it over with the team - thanks for the suggestion!
