What are the potential pitfalls of using the <?=SID?> syntax in PHP for passing session IDs in URLs?

Using the <?=SID?> syntax in PHP for passing session IDs in URLs can expose the session ID to potential security risks, such as session hijacking or session fixation attacks. It is recommended to use session cookies instead of passing session IDs in URLs to mitigate these risks.

&lt;?php
// Start the session
session_start();

// Use session cookies instead of passing session IDs in URLs
