4. Open your web browser and go to the URL where you uploaded the file, for example: http://www.yourwebsite.com/phpinfo.php
5. You should see a page with detailed information about the PHP configuration on your server, including the PHP version.
Another way to find out the PHP version is to contact your web hosting provider. Most web hosting control panels provide an option to view the PHP version that is installed on the server. You can also check the PHP version using the command line if you have access to your web server via SSH.
