What is a URL?

URL stands for Uniform Resource Locator. It is used to specify its location on a computer network and a mechanism for retrieving it. A URL is the fundamental network identification for any resource connected to the web (e.g., hypertext pages, images, and sound files).

URLs have the following format:

protocol://hostname/other_information

For example, the URL for w3resource's PHP basic exercises page is:

'https://www.w3resource.com/php-exercises/php-basic-exercises.php';

Sample Solution: -

PHP Code:

<?php
$url = 'https://www.w3resource.com/php-exercises/php-basic-exercises.php';
$url=parse_url($url);
echo 'Scheme : '.$url['scheme']."\n";
echo 'Host : '.$url['host']."\n";
echo 'Path : '.$url['path']."\n";
?>

Sample Output: 

Scheme : http                                               
Host : www.w3resource.com
