Are there any security risks associated with passing session cookies to PHP scripts in this manner?

Passing session cookies directly to PHP scripts can pose security risks, as it exposes sensitive session data to potential interception or manipulation. To mitigate this risk, it is recommended to use PHP's built-in session handling functions to manage session data securely. By utilizing session_start() at the beginning of each script and relying on PHP's session management functionality, you can ensure that session data is handled securely and efficiently.

<?php
session_start();

// Your PHP script code goes here
?>
