Dear all,

Concerning three session variables, it can work in PHP Version 4.0.4pl1, However it seems not OK in PHP Version 4.3.1 with only two of three variables valid when debug the program. Why? Please give me possible solution, thanks

Hey,maybe I can help you out.

In PHP 4.3.1,if you want to register a session,you should do the following:

session_start();
$_SESSION["test"]=1;

I have read some books which taught me to register session in an older way like this:
session_register("test");
However,it has many problems with that.So,I think you should try my method to register a session.

To unregister this session:
unset($_SESSION["test"]);

I hope I have done what you wanna do.🙂

Anyway, the problem still exists after revised to $_SESSION["test"]=1; , Why? I hope to receive your favourable very soon.

session_start() needs to be the very first line

Dr_Freak2

As ScubaKing22 said,you should put session_start(); at the very first line (No space before session_start()😉.

When you type this code,you should not output any text before you call this method.e.g. echo "Oh..."; / space before calling this method.

I hope this helps.🙂

When <?session_start();?>

is put the first line the following warning is prompted out, why?

Sincerely yours,

Simon

Is there any space before the "<?" ?

No http headers can be sent to the browser after you've started sending anything else - a single space counts as "anything else".

Reading your error messages, I see that this script (aconfirm.php) is being included by another (update.php). That other script is generating output on its first line.
