file, check if there are PHP module references to update.Open the XAMPP Control Panel and restart Apache. Now, let’s confirm the upgrade:
<?php
// Save this as info.php inside your xampp/htdocs folder
phpinfo();
?>
Visit http://localhost/info.php
in your browser. You should see a shiny new PHP version at the top!
Some legacy code may use functions deprecated in the latest PHP. Test your projects! For example:
<?php
// Old way that might break
$var = split(',', "red,green,blue");
// New way
$var = explode(',', "red,green,blue");
?>
Watch out for such differences and update your code as needed—this builds your troubleshooting and developer chops!

Upgrading your PHP version gives you access to improved speed, better security, and the latest features. Many popular frameworks and CMSs require modern PHP versions, so staying updated helps avoid compatibility issues and keeps your development environment secure.
To upgrade, first download the latest PHP 'Thread Safe' ZIP file for your system. Rename your existing XAMPP php folder for backup, add the new PHP folder, copy needed config files and extensions, update Apache configs if necessary, and then restart XAMPP to complete the upgrade.
If your projects stop working, it may be due to deprecated functions or changes in PHP. Carefully review error messages, check your code for outdated features, and update them as needed. Testing with a simple info page or basic script can help identify issues early.
After restarting XAMPP, create a file named info.php in the htdocs folder with the phpinfo() function. Visit http://localhost/info.php in your browser—if you see the new PHP version shown at the top, the upgrade was successful.
Using the latest PHP version means better performance, stronger security, and access to the newest features. It also ensures that your local setup closely matches modern web servers, making deployment smoother and reducing the risk of issues when taking projects live.
