What are the usability issues associated with hiding the full URL in PHP websites?

Hiding the full URL in PHP websites can lead to usability issues as users may not be able to easily identify the exact page they are on or share the URL with others. To solve this issue, it is recommended to display the full URL in a user-friendly manner, such as in a breadcrumb navigation or a clearly visible address bar.

<?php
// Displaying the full URL in a user-friendly manner
$current_url = "http://$_SERVER[HTTP_HOST]$_SERVER[REQUEST_URI]";
echo "You are currently on: " . $current_url;
?>
