Installing and running older PHP versions

(Note: Homebrew removes unsupported PHP versions, if you need something really old, get binaries from https://php-osx.liip.ch)
Sometimes you want to test your software against older PHP.

Here is how to set it up PHP7.2 (thanks Mike):
brew install php@7.2

$(brew --prefix php@7.2)/bin/pecl install --force xdebug
$(brew --prefix php@7.2)/bin/php -S 127.0.0.1:8080

Here you can run phpunit with older PHP version:
$(brew --prefix php@7.2)/bin/php vendor/bin/phpunit

To switch default PHP version entirely:
php unlink php
php link php@7.2
php --version

Next, lets switch back to latest PHP:
brew unlink php@7.2
brew link php

PHPStorm can be configured with multiple PHP versions.
