How to Change Composer’s PHP Version: A Step-by-Step Guide

Hey there, fellow Mac users! 🖐️ Are you looking to change the PHP version that Composer uses on your beloved machine? Well, you’ve come to the right place! In this casual, friendly, and informative guide, I’ll walk you through the step-by-step process of checking and changing the PHP version that Composer relies on. So, let’s dive right in and get your Composer setup running smoothly!

To begin, let’s determine the PHP version your Composer currently uses. Open up your favorite Terminal application on your Mac and type the following command:

$ php -v

Voila! You’ll now see the details of your current PHP version displayed on your screen. Make a note of it for future reference.

Now that we know our current PHP version let’s explore how we can install and manage multiple PHP versions using Homebrew, a package manager for macOS.

First, ensure you have Homebrew installed on your Mac. If not, visit the official Homebrew website and follow the installation instructions provided there.

Next, open your Terminal application and run the following command to update Homebrew:

$ brew update

Once Homebrew is updated, you can proceed to install the desired PHP version. For instance, if you want to install PHP 8.0, run the following command:

$ brew install php@8.0

Homebrew will now download and install the specified PHP version on your Mac. This process might take a few moments, so grab a cup of coffee while you wait ☕.

Error: php@7.4 has been disabled because it is a versioned formula!

$ brew tap shivammathur/php
$ brew install shivammathur/php/php@7.4

With multiple PHP versions at our disposal, let’s configure Composer to use the desired version.

Run the following command to check the installed PHP versions:

$ brew list | grep php

This command will display a list of PHP versions installed via Homebrew. Note down the version you wish to use with Composer.

To change the PHP version that Composer uses, we need to unlink the current version, then link the new version using the following commands:

$ brew unlink php@7.4
$ brew link php@8.0

Congratulations 🎉 You’ve successfully updated the PHP version that Composer will utilize.

Wrapping Up

And there you have it, dear Mac users! You’ve mastered the art of checking and changing the PHP version that Composer uses on your trusty machine. Now you can ensure compatibility with your projects and take full advantage of the latest PHP features and enhancements.

Remember, being able to manage different PHP versions gives you the flexibility to work on various projects without any hiccups. So, embrace the power of Homebrew, tinker with different PHP versions, and make Composer dance to your coding symphony!

Happy coding! 🎉✨
