How can PHP developers ensure proper session management when navigating between different pages within a web application, as discussed in the forum thread?

PHP developers can ensure proper session management by starting the session on each page where session data is needed and properly destroying the session when it is no longer needed. This can be achieved by using session_start() at the beginning of each page and session_destroy() at the end of each page or when the user logs out.

// Start the session
session_start();

// Perform actions with session data

// Destroy the session when it is no longer needed
session_destroy();
