What is the purpose of passing the session_id through a link in PHP?

Passing the session_id through a link in PHP is useful when you want to maintain the same session across different pages or when transferring session data between pages. This can be helpful in scenarios where you need to maintain session state while navigating through different parts of a website or when sharing session data between different domains. 

<?php
session_start();

// Get the current session ID
$session_id = session_id();

// Pass the session ID through a link
echo '<a href="next_page.php?session_id=' . $session_id . '">Next Page</a>';
?>
