Downgrading from the Official PHP Website

You may have attempted to directly download the latest PHP version from the official PHP site. However, simply replacing the binary file is insufficient for upgrading PHP in XAMPP.

The Backup and Upgrade Process

To ensure a seamless upgrade:

1. Backup your data: Create backups of your htdocs folder (the root directory for your websites) and the data folder within the MySQL folder (to preserve your database content).
2. Uninstall XAMPP: Uninstall the existing XAMPP installation using the Control Panel.
3. Reinstall XAMPP with the new PHP version: Download and install the XAMPP version that includes the updated PHP version.
4. Replace backed-up folders: Replace the htdocs and data folders from your backup in the corresponding locations within the new XAMPP installation.

Note: If you have modified any configuration files (e.g., php.ini, httpd.conf), make backup copies and restore them after the installation.

Verification

Once you have completed these steps, run "phpinfo()" within a PHP script or access the PHP information page in your web browser (http://localhost/phpinfo.php). You should now see the updated PHP version displayed.

Remember, upgrading PHP is a crucial step in maintaining your XAMPP environment. By following these instructions, you can ensure a smooth and successful upgrade process, empowering your applications to leverage the latest PHP capabilities.
