unset() and the $_SESSION array....

My multidimensional shopping cart will not remove an item from the basket. I read in the manual that unset() operates on a copy of the array in question within a function, but am a little lost because this is directly from the script....

//in a doubled "for" loop
if ($qty=='0') {
         //debug stuff here  

         //echo "quantity was zero...<br>$color = color<br>D is $d<br><br>";
                        unset($_SESSION['cart']['$d']['qty']);
                        // again...echo "qty should be unset<br>";
                        unset($_SESSION['cart']['$d']['size']);
                        unset($_SESSION['cart']['$d']['price']);
                        unset($_SESSION['cart']['$d']['color']);
                        unset($_SESSION['cart']['$d']['sku']);
                        unset($_SESSION['cart']['$d']);
}

My first thought was that one "unset()" should do it (the last one...) but my output is still showing the same number of entries in the cart. Hmm, I am using a function to do the output...

Any thoughts?

What you've got looks fine, all those variables should be unset...

I'm not the expert on sessions, but if I am correct, session variables are global variables, and I don't think you can unset a global variable. Not 100% sure though.
