Multiple PHP Versions in XAMPP: A Comprehensive Guide

Introduction

XAMPP, the popular web development environment, typically runs on a single PHP version. However, developers may encounter scenarios where multiple PHP versions are required. This article explores various ways to run multiple PHP versions on XAMPP, ensuring compatibility with both legacy and current projects.

Option 1: Directory-Specific PHP Versions

For projects requiring different PHP versions, you can configure specific directories to run on a particular version.

Step 1: Install and Configure Additional PHP Versions

Download older PHP versions from php.net and extract them to designated directories (e.g., C:xamppphp56). Modify the php.ini file in the extracted directory to enable extensions.

Step 2: Configure Apache

Edit the httpd-xampp.conf file and add the following code to the bottom:

Step 3: Set Directories to Run on Specific PHP Versions

Within httpd-xampp.conf, add the following for each directory you want to use the older PHP version:

Option 2: Separate Port for Older PHP Version

To run an older PHP version on a different port, add the following code to the bottom of httpd-xampp.conf:

You can access this version at http://localhost:8056/.

Option 3: Virtualhost for Older PHP Version

To create a virtualhost (e.g., localhost56) using an older PHP version, create a directory (e.g., htdocs56), add localhost56 to your hosts file, and add the following to httpd-xampp.conf:

You can now access this virtualhost at http://localhost56/.

With these methods, you can seamlessly utilize multiple PHP versions in XAMPP, ensuring compatibility with various projects while not sacrificing development efficiency.
