Thanks to a reddit post I made about this series ( / php_74_in_action_php_9_series_youtube_tuto... )
I was made aware of two corrections I need rectification from lesson 1 PHP 7.4 Class Property Types and Lesson 9: PHP 7.4 Serialize and Unserialize Magic Methods. Let's dive in and learn about PHP 7.4's declare(strict_types) global function for setting the class property types strict mode and the actual purpose of PHP 7.4's __serialize and __unserialize magic methods.
