How can developers verify the source code in PHP to understand how SIDs are generated in sessions?

Developers can verify the source code in PHP by checking the session_start() function to understand how SIDs are generated in sessions. By examining the session ID generation process in the PHP configuration files, developers can gain insights into how SIDs are created and managed during session initialization.

<?php
// Start the session
session_start();

// Get the current session ID
$session_id = session_id();

// Output the session ID
echo "Session ID: " . $session_id;
?>
