Are there any potential issues with displaying the Session ID multiple times in PHP and how can it be controlled?

Displaying the Session ID multiple times in PHP can potentially expose sensitive information and pose a security risk. To control this, you can limit the display of the Session ID to only when necessary, such as during debugging or logging, and ensure that it is not exposed to the end user. 

<?php
// Display Session ID only for debugging purposes
if (defined('DEBUG_MODE') && DEBUG_MODE) {
    echo "Session ID: " . session_id();
}
?>
