PHP is a server scripting language, and It is a powerful tool for making interactive and dynamic Web-pages. I have used WampServer 2.2 for following excercise..

<?php
echo "Your User Agent is :" . $_SERVER ['HTTP_USER_AGENT'];
?>

Result:

Your User Agent is : Mozilla/0.5(WindowNT 6.1;Win64;x64)AppleWebKit/537.36(KHTML,like Gecko)Chrome/67.0.3396.99 Safari/537.36
