I don't understand why it is necessary to use $topicIDs = array() on page 448.

There is a query :

'INSERT INTO mismatch_response (user_id, topic_id) VALUES ('" . $_SESSION['user_id']. "', '$topic_id')";

couldn't we just avoid using the $topicIDs array and just say:

"INSERT INTO mismatch_response (user_id, topic_id) VALUES ('" . $_SESSION['user_id']. "', $row[''topic_id'])";


I am sorry if this is a stupid question, but I am a newbie who feels really confused by this.

Your help is greatly appreciated.
