Michael Dyrynda, one of the two new hosts of the Laravel Podcast, share a nice tip on how to quickly switch PHP versions when using Laravel Valet.

At the time of writing, Laravel Valet ships with PHP 7.1 but if you're like me, you have some legacy projects around the place that haven't quite lifted their dependencies to PHP 7 just yet. A lot of folks might have previously used a VirtualBox Virtual Machine, or more recently considered Docker but a lot of the time and especially when dealing with simpler situations, Valet may be all that you need.
