Upgrade PHP 7.4 with Homebrew

PHP 7.4 came out this week, so it's time to upgrade! 

On Mac, Homebrew makes the whole process painless.

First, run an update on Homebrew:

brew update

You will see any tabs available if you've updated recently then its likely you'll only see:

Updated 1 tap (homebrew/core).
==> New Formulae
php@7.3

Next upgrade PHP:

brew upgrade php

This will upgrade PHP to the latest version, which at this moment is PHP 7.4

To verify your PHP version run:

php -v

Then you should see:

PHP 7.4.0 (cli) (built: Nov 29 2019 16:18:44) ( NTS )
Copyright (c) The PHP Group
Zend Engine v3.4.0, Copyright (c) Zend Technologies
    with Zend OPcache v7.4.0, Copyright (c), by Zend Technologies

That's all there is to it!
