Now that WordPress has committed to a minimum requirement of PHP 7 by the end of 2019, we can all start looking at modernising the code we maintain. Removing hacks to support old versions is easy, but how can code be improved when it just works on PHP 7? Namespaces, generators, Intl are just a few of the features introduced since PHP 5.2, not to mention scalar type declarations and all the other awesomeness that came with PHP 7. But what does it all mean, and how can you take advantage of these goodies? Join Juliette to learn to identify where to make quick fixes, when to look into refactoring, and how to make your code faster, better and more secure by using modern PHP.
