Brent has done a writeup on how to upgrade your Homebrew-installed PHP version to PHP 7.4. Since the php
formula now contains that 7.4 version (instead of 7.3 before), all you need to do is make sure brew is up-to-date and then upgrade the php
formula itself:
# make sure brew is up-to-date
brew update
# upgrade the php formula to its latest version
brew upgrade php
Upgrade to PHP 7.4 with Homebrew on Mac →
💁♂️ Don’t forget to upgrade Valet too, while you’re at it:
# stop current valet
valet stop
# update global packages
composer global update
# Make Valet do its housekeeping
valet install
