How can adding '.SID.' to all links in a PHP website help maintain session continuity and prevent users from losing their session ID?

When users navigate through a PHP website, their session ID is typically stored in a cookie. If a user clicks on a link that does not include their session ID, they may lose their current session and have to log in again. By adding '.SID.' to all links in a PHP website, we can ensure that the session ID is passed along with every request, maintaining session continuity and preventing users from losing their session. 

<?php
// Add '.SID.' to all links in a PHP website
function add_session_id_to_links($html) {
    return preg_replace('/<a(.*?)href="(.*?)"(.*?)>/i', '<a$1href="$2' . (strpos($2, '?') === false ? '?' : '&') . SID . '"$3>', $html);
}

// Example usage
$html = '<a href="page.php">Link</a>';
echo add_session_id_to_links($html);
?>
