PHP 7.3 has been out for a couple of weeks now and if you're interested in upgrading, the process is super simple.
Note: This small guide if meant for Mac OS users. If you're a Windows user, a quick google search should help you out!
To pull install or update any applications or services, I use a Mac OS package manager called Homebrew. Before we go about upgrading our PHP installation, lets' quickly run a Homebrew commands to update our formulae and Homebrew itself.
$ brew update
Now that our formulae is updated, we can proceed to upgrade our PHP installation with the latest version available on Homebrew.
$ brew upgrade php
After the upgrade completes, you can open a new tab in your terminal and check your PHP version with
php -v. If all went well, you should see something like this:
PHP 7.3.0 (cli) (built: Dec 7 2018 11:00:11) ( NTS ) Copyright (c) 1997-2018 The PHP Group Zend Engine v3.3.0-dev, Copyright (c) 1998-2018 Zend Technologies with Zend OPcache v7.3.0, Copyright (c) 1999-2018, by Zend Technologies
In only a couple of minutes, you're already upgraded to the latest version of PHP. Keep in mind that some packages or services you're using in your system or applications might not be updated just yet to work on PHP 7.3.
If you're a Laravel user you're more than likely using Laravel Valet. In order to get Valet working on PHP 7.3, you simply need to update it to the latest version released. Just do a
composer global update to update all your globally installed Composer packages and then just do a
valet install again is necesarry to configure the installation to work with your new PHP version.
Warning: There are some known bugs with PHP 7.3 and Opcache when queueing emails in the Laravel framework so I encourage you to keep an eye on the issues in the Laravel repository on Github.
