22. Get Full URL

Write a PHP script to get the full URL.

Sample Solution:

PHP Code:

<?php
// Constructing the full URL using $_SERVER variables
$full_url = "http://$_SERVER[HTTP_HOST]$_SERVER[REQUEST_URI]";

// Display the constructed full URL
echo $full_url . "\n";
?>

Explanation:

• Constructing the Full URL:
• The code constructs the full URL by concatenating several $_SERVER variables:
• $_SERVER['HTTP_HOST'] retrieves the host name (e.g., www.example.com).
• $_SERVER['REQUEST_URI'] retrieves the URI (the path and query string) of the current request (e.g., /path/to/page?query=string).
• The full URL is formed as "http://<host><uri>" and stored in the variable $full_url.
• Display the Full URL:
• The echo statement outputs the constructed full URL, followed by a newline (\n).

Output:
