Tomas Votruba: How to Get PHP 7.4 Typed Properties to Your Code in Few Seconds

Tomas Votruba has a new post to his site showing you how you can get typed properties in your code "in a few seconds", a feature coming in the next major version of the language, PHP 7.4.

PHP 5.6 and 7.0 is going to be dangerous since 2019, PHP 7.1 is new baseline and PHP 7.3 is just about to be released in the end of 2018.

Is this the best time to upgrade your code to PHP 7.4?

He starts off by talking about the use of the @var annotation (DocBlock format) and how, while they can be informative, do nothing functionally speaking. He shows how to shift this over to a typed property, forcing the value to be an integer. He also covers current use of "best practices" when it comes to typing properties and how to think about future compatibility. He ends the post with the command you'd need to use - making use of the rector reformatter - to shift all of those @var annotations over to actual typed properties.
