This script is called checkid.php

First, we use the session_start() function. Then we ensure that the session id variable is set by checking it, and send the user to Register Group with Captcha if it is not, after running the session_unset() function to free all of the user's session variables and session_destroy() to destroy all data registered to the user's session. Then we use header('location: register-with-captcha.php') to send the user to Register Group with Captcha.

Finally we use an else statement if the session id variable IS set, because the session is OK and the user is logged in. The else does not do a thing except be an alternative to all of the above, which is why the else leads only to a comment.

The script below is called: checkid.php

<?php

session_start();

if(!isset($_SESSION['sessionid'])){

session_unset();

session_destroy();

header('location: register-with-captcha.php');

}else{
// session logged
}

?>
