How can examining HTTP headers help in identifying and resolving session management issues in PHP applications?

Examining HTTP headers can help in identifying and resolving session management issues in PHP applications by providing information about the current session status, such as session ID, expiration time, and whether cookies are being used to manage sessions. By analyzing these headers, developers can pinpoint issues like session hijacking, expired sessions, or misconfigured session settings, and take appropriate steps to fix them. 

// Check session status using HTTP headers
if (isset($_SERVER['HTTP_COOKIE'])) {
    // Session ID is present in the cookie header
    echo "Session ID: " . $_COOKIE[session_name()];
} else {
    // No session ID found in the cookie header
    echo "No active session found";
}
