Now that PHP 8.2 has been released, it's time to upgrade the PHP of your Mac.

If you're using Brew - which you probably are - there are only a few steps involved.

Issue these commands

# let's make sure brew is up to date
brew update

# install php
brew tap shivammathur/php
brew install shivammathur/php/php@8.2

That's it! You can check the version of PHP you are running with this command.

php -v

This should output PHP 8.2.

Upgrading Laravel Valet

Here are some extra steps for Laravel Valet users to ensure you run your local websites on PHP 8.2.

I've noticed that Laravel Valet will not immediately pick up on the installed PHP 8.2

To upgrade, I ensured I was running the latest version of Valet.

composer global update

Next, you can force Valet to switch to php@8.2 using this command.

valet use php@8.2 --force

If you now add phpinfo() to one of your hosted sites, it should output PHP 8.2

And that's all there is to it!

EDIT: I haven't tested this but apparantly Laravel Valet users can upgrade to PHP 8.2 by issuing a single command.

FYI 8.2 will be pulled in automatically if you issue the “valet use php@8.2” command.
