How can storing IP addresses in session management be problematic in PHP?

Storing IP addresses in session management can be problematic in PHP because IP addresses can change, especially for users on mobile devices or using VPNs. This can lead to session errors or security vulnerabilities if the stored IP address no longer matches the user's current IP. To solve this issue, it's recommended to avoid storing IP addresses in session management and instead rely on other session identifiers like session IDs. 

// Avoid storing IP addresses in session management
// Use session IDs as the primary session identifier

session_start();

// Set session ID
$session_id = session_id();

// Store session ID in session management
$_SESSION['session_id'] = $session_id;
