Installing PHP8.0 on macOS

If you take a look at the PHP supported versions, PHP8.0 is not currently supported.

If you try to install with brew, you are going to get an error:

$ brew install php@8.0

Error: php@8.0 has been disabled because it is a versioned formula!

At the official website, you can see it disabled.

If you need to use this version, or a previous one, between 5.6 and the last supported, you can use a different tap. To do this, you need to add the tap:

brew tap shivammathur/php

Then you have to install the desired version:

brew install shivammathur/php/php@8.0

And now you have this unsupported version installed on your macOS:

php -v
PHP 8.0.30 (cli) (built: Aug  3 2023 17:13:08) ( NTS )
