How can PHP developers effectively balance the need for session regeneration with the risk of losing important session data during the process?

When balancing the need for session regeneration with the risk of losing important session data, PHP developers can implement a strategy where they store critical session data in a separate variable before regenerating the session ID. This way, they can reassign the crucial data back to the new session ID after regeneration, ensuring that important information is not lost in the process. 

// Store critical session data in a separate variable
$criticalData = $_SESSION['critical_data'];

// Regenerate the session ID
session_regenerate_id();

// Reassign the critical data back to the new session ID
$_SESSION['critical_data'] = $criticalData;
