Write a PHP script, which will return the following components of the url 'https://www.w3resource.com/php-exercises/php-basic-exercises.php'.

List of components : Scheme, Host, Path

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
// Define the URL to be parsed
$url = 'https://www.w3resource.com/php-exercises/php-basic-exercises.php';

// Parse the URL and store its components in the $url variable
$url = parse_url($url);

// Display the scheme (protocol) of the parsed URL
echo 'Scheme : ' . $url['scheme'] . "\n";

// Display the host (domain) of the parsed URL
echo 'Host : ' . $url['host'] . "\n";

// Display the path of the parsed URL
echo 'Path : ' . $url['path'] . "\n";
?>

Sample Output:

Scheme : http                                               
Host : www.w3resource.com                                   
Path : /php-exercises/php-basic-exercises.php

Explanation:

Here's a brief explanation of the above exercise:

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

Defines a URL string to be parsed.

$url = parse_url($url);

Parses the defined URL using the "parse_url()" function and stores the components (scheme, host, path, etc.) in the '$url' variable.

echo 'Scheme : ' . $url['scheme'] . "\n";

Displays the scheme (protocol) of the parsed URL.

echo 'Host : ' . $url['host'] . "\n";

Displays the host (domain) of the parsed URL.

echo 'Path : ' . $url['path'] . "\n";

Displays the path of the parsed URL.
