    You should specify the php version you are about to unlink.

    For example:
    brew unlink [email protected]

    If you do have PHP 8 installed it might not have been via brew. As you did not say which operating system you are using it’s impossible for us to know how it was originally installed.

    However, PHP 7 is now obsolete so you will not be able to install it directly using brew, it will give you an error message.

    You can install PHP 7 on a Mac using the brew tap shivammathur/php which you install first

    brew tap shivammathur/php

    followed by the command to install PHP

    brew install shivammathur/php/[email protected]

    then set up your path

    echo 'export PATH="/opt/homebrew/opt/[email protected]/bin:$PATH"' >> ~/.zshrc
echo 'export PATH="/opt/homebrew/opt/[email protected]/sbin:$PATH"' >> ~/.zshrc
