How can the PHP function session_name() impact session management and logout functionality?

When using session_name(), it is important to note that changing the session name can impact session management and logout functionality. If the session name is changed during the logout process, it can result in the user's session not being properly destroyed, leading to potential security risks. To address this issue, ensure that the session name is not changed during the logout process. If you need to set a custom session name, do so at the beginning of the session before any user interactions occur.

// Set custom session name at the beginning of the session
session_name('custom_session_name');
session_start();

// Logout functionality without changing the session name
session_unset();
session_destroy();
