3 min read 08-10-2024

Upgrading PHP in XAMPP on a Windows machine can be a daunting task for many developers. However, it is crucial to keep your PHP version updated to leverage the latest features, improvements, and security patches. This article will guide you through the process of upgrading PHP in XAMPP in a clear and easy-to-understand manner.

Understanding the Need for Upgrading PHP

Upgrading PHP is essential not just for performance improvements, but also for security. Each new PHP version comes with bug fixes, deprecation of old features, and the introduction of new functionalities. Running an outdated version can expose your applications to vulnerabilities and limit your ability to use modern programming practices.

The Upgrade Scenario

Imagine you’re using XAMPP with PHP version 7.4 and you want to upgrade to PHP 8.0 to take advantage of its new features. You could face potential compatibility issues with your existing applications, but with a systematic approach, you can perform this upgrade smoothly.

Original Code

Before we dive into the upgrade process, let’s take a look at a simple PHP code snippet that demonstrates some fundamental PHP functionalities:

<?php
echo "Hello, World!";
?>

Now, let’s go through the steps to upgrade your PHP version in XAMPP.

Steps to Upgrade PHP in XAMPP for Windows

Step 1: Backup Your Current Environment

Before making any changes, it is imperative to back up your XAMPP environment. Create a copy of your entire XAMPP directory and your databases to ensure you can restore your previous setup if something goes wrong.

Step 2: Download the Latest PHP Version

Go to the official PHP website: PHP Downloads.
Choose the latest stable version of PHP (e.g., PHP 8.0) and download the appropriate Thread Safe zip package for Windows.

Step 3: Extract the Downloaded PHP Files

Navigate to the folder where you downloaded the PHP package.
Extract the contents of the zip file to a new folder named php8 (or any desired name) inside the C:\xampp directory.

Step 4: Configure PHP in XAMPP

Open the XAMPP Control Panel and stop the Apache server.
Navigate to C:\xampp\php and rename the existing php folder to something like php_old as a precaution.
Rename the new PHP folder (e.g., php8) to php.

Step 5: Update the php.ini File

Copy the php.ini-development or php.ini-production file from the old php_old directory to the new php directory.
Open the php.ini file in a text editor and adjust your settings as needed (e.g., enabling extensions).
Ensure you have your extensions set according to your previous setup.

Step 6: Update the Apache Configuration

Open the httpd-xampp.conf file located in C:\xampp\apache\conf\extra.

Look for the line that specifies the PHP directory:

LoadModule php7_module "C:/xampp/php/php7apache2_4.dll"

Update the line to reflect the new PHP version:

LoadModule php8_module "C:/xampp/php/php8apache2_4.dll"

Step 7: Restart Apache Server

Go back to the XAMPP Control Panel and start the Apache server. If all configurations are correct, your server should start without any issues.

Step 8: Verify the PHP Upgrade

Create a new PHP file in the C:\xampp\htdocs directory:
```
<?php
phpinfo();
?>
```
Access this file via your browser by navigating to http://localhost/yourfilename.php. You should see the PHP information page displaying the new version.

Additional Insights

When upgrading PHP, it's also a good practice to check the compatibility of your existing applications with the new PHP version. Use tools like the PHP Compatibility Checker to analyze your codebase for potential issues.

Conclusion

Upgrading PHP in XAMPP on Windows is an essential task for any developer looking to maintain performance and security. By following the outlined steps, you can successfully upgrade your PHP version without much hassle.
