How to Upgrade PHP Version in XAMPP: A Comprehensive Guide

Why Upgrade PHP in XAMPP?

Upgrading PHP in XAMPP is essential for several reasons. For instance, newer versions offer improved performance, enhanced security, and modern features. Moreover, many frameworks like Laravel require PHP 7.4 or higher. Therefore, keeping PHP updated ensures compatibility and efficiency.

Prerequisites

Before you begin, ensure you have:

• XAMPP installed (e.g., C:\xampp on Windows).
• Administrative privileges.
• A backup of your XAMPP setup.
• Internet access to download PHP from PHP.net.

Step-by-Step Guide

Step 1: Check Current PHP Version

First, verify your current PHP version:

1. Start XAMPP and launch Apache/MySQL.
2. Create info.php in C:\xampp\htdocs: <?php phpinfo(); ?>
3. Visit http://localhost/info.php to see the version (e.g., PHP 7.4).

Step 2: Download New PHP Version

Next, download the desired PHP version:

1. Visit PHP.net or Windows PHP.
2. Choose a Thread Safe (TS) build for Windows (e.g., PHP 8.1, x64).
3. For macOS/Linux, use Homebrew or source code.

Step 3: Back Up XAMPP

Before proceeding, back up your setup:

1. Stop Apache and MySQL in XAMPP.
2. Copy C:\xampp\php to C:\xampp\php_backup.
3. Save php.ini and C:\xampp\htdocs files.

Step 4: Replace PHP Folder

Now, replace the PHP folder:

1. Extract the downloaded PHP ZIP (e.g., to C:\php-8.1).
2. Rename C:\xampp\php to php_old.
3. Move the extracted folder to C:\xampp\php.

Step 5: Configure the New PHP Version

Subsequently, configure PHP:

1. Copy php.ini from backup or rename php.ini-development to php.ini.
2. Enable extensions in php.ini: extension=gd extension=pdo_mysql
3. Update Windows Path variable to include C:\xampp\php.

Step 6: Update Apache

Meanwhile, adjust Apache settings:

1. Open C:\xampp\apache\conf\extra\httpd-xampp.conf.
2. Update the PHP module: LoadModule php8_module "C:/xampp/php/php8apache2_4.dll"
3. Ensure PHPIniDir "C:/xampp/php".

Step 7: Test the Upgrade

Finally, test the new version:

1. Start Apache and MySQL.
2. Check http://localhost/info.php for the new version.
3. Test your projects for compatibility.

Step 8: Troubleshoot Common Issues

If problems occur, try these solutions:

• Apache Fails: Verify the PHP module path in httpd-xampp.conf.
• Missing Extensions: Enable them in php.ini.
• Deprecated Code: Update your scripts for new PHP versions.

Notes for macOS/Linux

For macOS, use Homebrew (brew install php@8.1) and update /Applications/XAMPP/xamppfiles/php. On Linux, adjust /opt/lampp/php. Consult XAMPP’s Linux guide for details.

Best Practices

• Regularly back up XAMPP.
• Test upgrades in a separate environment.
