How to Install Multiple Versions of PHP on Mac

If you’re a developer or work with different PHP frameworks or projects, you may need to install multiple versions of PHP on your Mac. Having multiple PHP versions allows you to test your code on different versions and ensure compatibility. In this article, we will guide you through the process of installing multiple versions of PHP on your Mac.

Install Homebrew

1. Install Homebrew

Homebrew is a package manager that simplifies the installation of software on macOS. To install multiple versions of PHP, we will use Homebrew. Open the Terminal application on your Mac and run the following command to install Homebrew:

/bin/bash -c “$(curl -fsSL

2. Install PHP Versions

Once Homebrew is installed, you can proceed to install multiple versions of PHP. In the Terminal, run the following command to see the available PHP versions: 

brew search php

This will display a list of PHP versions that you can install. Choose the versions you need for your development environment and install them using the following command:

brew install php@version

Replace “version” with the desired PHP version, such as php@7.4 or php@8.0. Repeat this command for each PHP version you want to install.

3. Switching Between PHP Versions

After installing multiple PHP versions, you can switch between them based on your project requirements. Homebrew provides a convenient tool called brew link to manage different versions. In the Terminal, run the following command to list the installed PHP versions:

brew list –versions php

This will display the installed PHP versions along with their respective paths. To switch to a specific version, use the brew link command followed by the version number. For example, to switch to PHP 7.4, run:

brew link php@7.4 –overwrite –force

This will set the PHP 7.4 version as the default one for the current shell session.

4. Updating PHP Versions

Over time, new versions of PHP are released with bug fixes and security patches. To keep your PHP versions up to date, you can use Homebrew to update them. In the Terminal, run the following command to update PHP:

brew update && brew upgrade php

This will update all installed PHP versions to the latest available version.

5. Configuring Web Server

To use the different PHP versions with your web servers, such as Apache or Nginx, you need to configure the server to recognize and use the desired PHP version. The configuration process varies depending on the web server you are using. Consult the documentation of your specific web server to learn how to configure it for different PHP versions.

Installing multiple versions of PHP on your Mac allows you to work with different PHP frameworks and projects efficiently. By following the steps outlined in this guide, you can easily install, switch between, and update multiple PHP versions using Homebrew. Remember to configure your web server to use the desired PHP version for your projects. With this flexibility, you can ensure compatibility and test your code on different PHP versions, ultimately improving the quality of your PHP development on macOS.
