$PHPSESSID not recognised

vampyre

I'm going through the code in the book 'php essentials' and this error has come up:

'Undefined variable: PHPSESSID'

the code stops at the second line of the following so I won't bore with details:

<?php
session_start();
if (!$PHPSESSID) {

        .........

        }
        else  {

        .........

        }

<HTML>

blah, blah, blah.........

Anyone seen this before and can help? I would love to work out what must eb a simple answer 🙂

Try using session_id() instead of $PHPSESSID. I forget which array it's stored in (if it is) so I can't say what to susbtitute for '' in $_['PHPSESSID'].

Great, that worked a treat 🙂

<?php
if (!session_id())
{
session_start();
do this.....
}
else
{
do this...
}
?>

Thanks! If you do ever recall the full syntax for $_*['PHPSESSID'], I'd love to know.

Thanks again

php.net has full documentation 😉

Thanks.. Sometimes it's easier to ask a question from people with experience than wade through a ton of documentation
