Updating PHP in a macOS machine can be difficult, you cannot just install Xampp, MAMP, or WAMP, run it, and then you have PHP 8 in your machine, you have to go through some steps that we will be showing in this article.

If you want to upgrade to a version between 5.3 and 7.3

If so, there is an easy solution called “PHP for OS X”, which doesn’t support any version higher than PHP 7.3.

Upgrading to PHP 8

First things first, we have to install PHP on our machine

// Install PHP 8
// This will install the latest PHP version
brew install php
// To install a specific version, run this command:
brew install php@8.0

Now if we check the current PHP version, we will still see 7.1 or another one, which means we have to make the system consider PHP 8 as the default version, to do that we have to run this command:

brew link --force php@8.0

Restart the services:

brew services start php@8.0

we still cannot see PHP 8.0 when we run

php -v or php --version

2 commands are left to make this work:

export PATH="/usr/local/opt/php@8.0/bin:$PATH"
export PATH="/usr/local/opt/php@8.0/sbin:$PATH"

And voila, we have successfully installed PHP 8.0 on our machine

php -v
// Output:
PHP 8.0.9 (cli) (built: Aug 2 2021 22:56:15) ( NTS )
Copyright (c) The PHP GroupZend Engine v4.0.9, Copyright (c) Zend Technologieswith Zend OPcache v8.0.9, Copyright (c), by Zend Technologies

I passed 3 days trying to solve this and upgrade PHP from 7.1 to 8.0 in a 2011 MacBook, no results and suddenly I ran into this answer in StackOverflow which helped me a lot and I said why not share it with others!

I hope this helped.
