How many $_SESSION can I use?

[TomatoLover]

My question is how many $_SESSION variables can I use in a single page?

On my first page, I have two $SESSION variables, which work perfectly fine.

On the second page, I created two more $SESSION variables. It seems that verifying $SESSION variables on the second page works, but when it comes to query, it just doesn't work. It is supposed to redirect to the next page if the data matches with the $SESSION variables, and if not, it should display the "NO Match" message. But neither happens.
I am not sure if this has something to do with $_SESSION or not, but that's the only thing I could think of because query itself is correct.

Please help me!!!

$_SESSION is an array. As far as I know for any real purpose, realistically there is no limit to the size of this array.

I am new, but, as far as I can see you can only use one session per user interface to the site. The idea of a session is basically that of a cookie that is stored on the server instead of your PC.

You may want to search through some of the other threads before you post a question. I posted this same question a couple of days ago, others posted similar (but not the same question many times):

Here is the link in the PHP manual. I think they were introduced in version 4:

Hope this will answer your question.

Thanks for your reply.

But I just want to say that I had looked other posts for hours and coudn't find the answer that I was looking for. Otherwise, I didn't post this question.
