On Mac OSX, how do I simply switch between PHP versions?


I’d like to test my application on PHP versions 5.3 to 7.0.

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

If you have both versions of PHP installed, you may use the link and unlink brew instructions to switch between them.

To transition between PHP 7.4 and PHP 7.3, for example.

brew unlink php@7.4
brew link php@7.3

PS: For these commands to work, both versions of PHP must be installed.

This tutorial on how to install and switch PHP versions on OSX is really helpful.

I can change the version like this:

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

That’s exactly what I’m looking for!

Let’s say we want to upgrade from PHP 7.4 to PHP 7.3.

brew unlink php@7.4
brew install php@7.3
brew link php@7.3

If you encounter the message Warning: php@7.3 is keg-only and requires linking with —force, Then give this a shot:

brew link php@7.3 --force

Show current version

$ php -v

Change to a newer version (for example, from 5.5.x to 7.0.latest):

$ brew unlink php55
$ brew install php70

You may easily swap between PHP versions if you install it with homebrew. If you want php56 to refer to Version 5.6.17, simply type:

brew switch php56 5.6.17
