This is two pages. I wrote the code together. I tried to run the code normally. why is $ _ SESSION used here?
One page
$ _ SESSION ['Rs '] = $ rs;
Another page
Echo: '. $ _ SESSION ['Rs'];
This enables cross-page value transfer.
$ _ SESSION is used to pass values between pages.
One page
$ _ SESSION ['Rs '] = $ rs;
Another page
Echo: '. $ _ SESSION ['Rs'];
This enables cross-page value transfer.
$ _ SESSION ['Rs '] = $ rs;
Echo: '. $ _ SESSION ['Rs'];
Are these two sentences not on the same page?
One page
$ _ SESSION ['Rs '] = $ rs;
Another page
Echo: '. $ _ SESSION ['Rs'];
This enables cross-page value transfer.
The session is useless here. if I have gone all of them, I can also run it to pass the value through post.

You're right. it's useless here.
You said it all.This is two pages, but the code is written together.
You have changed people's code and asked them what they mean. Don't you think it's strange?
