Install PHP7.1 on OSX with homebrew

Last year I published this handy guide for installing PHP 7 on homebrew. This week, I went and bumped my local machine to the new 7.1 beta3^, and here’s how.

If you’ve already installed 7 locally, chances are you’ve already run a simple sudo xcodebuild -license to sort out Xcode’s license agreement.

Steps to upgrade

Update3 December 2016 — PHP 7.1 is now stable and this guide is updated accordingly.

Make sure brew is up to date:

brew update
brew upgrade

(I kinda helped make that update happen! Woo!)

If you’re not already running php7 then you may need:

brew tap homebrew/dupes
brew tap homebrew/versions
brew tap homebrew/homebrew-php

And then the complicated part:

brew unlink php70
brew install php71

And the result?

$ php --version
PHP 7.1.0 (cli) (built: Dec  2 2016 03:30:24) ( NTS )

Upgrade guides

Upgrading is always different for everyone and every project. Here’s a few links to help you update your project or library.

If you haven’t already ported your code to 7.0 you can also head over to the official migration guide from to review the full changes.

There’s also the official 7.1 migration guide – but remember its still a work in progress as a beta release.

As with last year’s guide, you’ll also find Travis CI supports the latest alpha’s. They’ve aliased 7.1 as one of their officially supported php versions.

Happy coding!
