Are there any built-in PHP functions or features that can help streamline session management?

Session management in PHP can be streamlined using built-in functions like session_start(), session_regenerate_id(), session_destroy(), and session_unset(). These functions help in starting a session, regenerating session IDs for security, destroying a session, and unsetting session variables respectively. By utilizing these functions effectively, developers can efficiently manage user sessions in their PHP applications.

// Start a session
session_start();

// Regenerate session ID for security
session_regenerate_id();

// Destroy a session
session_destroy();

// Unset session variables
session_unset();
