How can PHP be used to dynamically determine and display the current page a user is on within a paginated forum?

To dynamically determine and display the current page a user is on within a paginated forum, you can use PHP to retrieve the current page number from the URL parameters and display it to the user. This can be achieved by parsing the "page" parameter from the URL using the $_GET superglobal and then displaying this value to the user.

<?php
// Get the current page number from the URL parameter
$current_page = isset($_GET['page']) ? $_GET['page'] : 1;

// Display the current page number to the user
echo "You are currently on page " . $current_page;
?>
