How can I easily switch between PHP versions on Mac OSX?

Question

I would like to test my application on PHP 5.3 up to PHP 7.0.

Where and how can I install the versions and how can I switch them by running a small script?

Answer

If you have both versions of PHP installed, you can switch between versions using the link and unlink brew commands.

For example, to switch between PHP 7.4 and PHP 7.3

brew unlink php@7.4
brew link php@7.3

PS: both versions of PHP have be installed for these commands to work.
