[Resolved] "unset" is not unsetting!

[NoBullMan]

Hi,
can someone tell me why this unset is not unsetting the session variable and goes into an infinite loop?

foreach($_SESSION['cart'] as $itemid => $qty)
{
  if (true)
    unset ($_SESSION['cart'][$itemid];
}

There is only one item in the cart but it loops forever.

Thanx.

surely you can just do unset ($_SESSION['cart'])?

It looks like you have missed the closing bracket on the unset.

Code should be:

foreach($_SESSION['cart'] as $itemid => $qty) 
{ 
  if (true) 
    unset ($_SESSION['cart'][$itemid]); 
}

and what's with the if (true)?

thanks for the replies.
1. the "if (true)" is in fact some condition in my php file, I didn't want to bother you with the condition as it is not relevant.
2. The missing bracket is in my example here, in the code it is OK.
3. I don't want to unset the whole cart, just a single element in the cart. I am simply checking the content of the cart, if a condition is satisfied for that element I want to remove it from the cart (the condition being if the qty has been changed to zero.)

Thanx.
