Regarding the session issue, I followed the steps step by step, but the session values are different. I won't tell you what happened.

This teacher lectures too quickly. It is not a lecture at all. He is just doing his own thing, regardless of whether you know it or not. This session obviously only saved two values when it was started. Why does he save so many values. . . .
How to troubleshoot errors: You can check to see if the session is stored elsewhere in your code. If you are sure not, delete the other session values, and then re-execute your demo to see how many are stored.
