In this brief series, we’ll review one feature per episode to get you up to speed as quickly as possible.
Arrow Functions
PHP 7.4 includes support for arrow functions – or short closures – which allows for a shortened syntax for defining single lines closures with implicit scope binding.
Null Coalescing Assignment Operator
The null coalescing assignment operator (??=) is a fancy term for something that is quite simple to understand. It provides a shorthand for assigning a value to a variable only if it hasn’t been set already.

As part of PHP 7.4, you may now use the spread operator (…) within arrays.
