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
// Display the text "Your User Agent is :" followed by the user agent string from the HTTP request
echo "Your User Agent is :" . $_SERVER['HTTP_USER_AGENT'];
?>

Sample Output:

View the output in the browser

Explanation:

Here's a brief explanation of the above exercise:

• echo "Your User Agent is :" . $_SERVER['HTTP_USER_AGENT'];
• Outputs the text "Your User Agent is :" followed by the user agent string from the HTTP request. The user agent string typically contains information about the client's browser, operating system, and device.
