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:
