About this course

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

What PHP libraries does this tutorial use?

// composer.json

    }
}

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!
