PHP has continued to improve, year after year, decade after decade. PHP 4 to PHP 5 brought better object oriented features. PHP 5.2 - 5.6 brought speed improvements, language and syntax improvements and more. The transition from PHP 5 to PHP 6 brought great T-shirts, but other than that, literally nothing since it doesn't exist. In PHP 7, we get huge speed improvements, primitive type type-hints and return types. Building code with strong-typing allows several categories of bugs to be eliminated entirely.
This talk will introduce and cover several of PHP 7 and 7.1s more notable features, how they work, how you can use them and why writing PHP code is more fun and exciting now than it used to be.
