I am doing something like this on my home page, setting session variable.


if(!isset($_SESSION["id"]))
{
$cart_id = md5(uniqid(rand()));

$_SESSION['id'] = $cart_id;
}
**********

Someone told me i do not need to do this i should use

<?=SID?>

I did something like this but it did not print anything
echo "<?=SID?>";

thanks

No no, he meant not to print that text, but to just have:

<?=SID?>

in the middle of a PHP page (outside the <?php ?>)

What this does is echo the PHP session id variable. It is recommended that you instead use

<?php echo SID; ?>

to avoid use of short tags.

Read this page for more info about PHP session handling:

HTH!
