Is it possible to register the Session ID as a global variable in PHP?

To make the Session ID available as a global variable in PHP, you can store it in a global variable or in the $_SESSION superglobal array. Storing it in a global variable allows you to access it across different scripts within the same session. However, it is important to note that storing sensitive information like session IDs in global variables can pose security risks. 

<?php

session_start();

// Store the Session ID in a global variable
$_SESSION['session_id'] = session_id();

// Access the Session ID as a global variable
$session_id = $_SESSION['session_id'];

echo "Session ID: " . $session_id;

?>
