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

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?

Solution 1:

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 [email protected]
brew link [email protected]

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

Solution 2:

I found this very good tutorial on how to install and switch php versions on OSX.

I can switch the version like

$ sphp 7.0 => PHP 7.0
$ sphp 7.3 => PHP 7.3
$ sphp 7.4 => PHP 7.4

Exactly what I want!
