PHP Exercises : PHP browser detection script

PHP : Exercise-6 with Solution

Write a simple PHP browser detection script.

Sample Output : Your-User Agent is: Mozilla/5.0 (Windows NT 6.1) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/35.0.1916.114 Safari/537.36

Web browse: A web browser is a software application for accessing information on the World Wide Web. Each individual web page, image, and video is identified by a distinct URL. These URLs, enable browsers to retrieve and display them on the user's device. A web browser is not the same thing as a search engine, though the two are often confused. For a user, a search engine is just a website, such as google.com, that stores searchable data about other websites. But in order to connect to and display websites on their device, a user needs to have a web browser installed.

Sample Solution: -

PHP Code:

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

Sample Output:

View the output in the browser
