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

Question

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. . . .

Answer 1

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.
