How can PHP errors related to session management be debugged effectively?

PHP errors related to session management can be debugged effectively by checking for common issues such as session_start() not being called before accessing session variables, session variables being overwritten or unset unintentionally, or session data not being saved correctly. To debug these errors, you can use functions like session_status() to check the current session status, session_id() to get the current session ID, and session_save_path() to verify the session save path.

<?php
// Check if session is active
if (session_status() == PHP_SESSION_NONE) {
    session_start();
}

// Check current session ID
$session_id = session_id();
echo "Session ID: " . $session_id;

// Check session save path
$save_path = session_save_path();
echo "Session Save Path: " . $save_path;
?>
