<?php echo "The current PHP version being used is: "
. phpversion(); ?>Save this file as phpver.php to the same folder where all of your site files are located.
Then access this page in a browser using your domain and adding /phpver.php to the end of it (such as http://yourdomain.com/phpver.php) to view the output.
