[PHP-DEV] Shopping Cart

[[W]]

i got a script for a shopping cart, like this :
<?php
/*
Basket class for e-commerce purpose

Version : 0.4
Type:Class
Category:Shopping Carts
License: GNU General Public License

Description: This class provides methods for add, remove, update and remove
all items
from a basket. The basket works with a session cookie, saving the product ID
and quantity in an array for simple accesing it.
There's an example in this category... called "Basket example using basket
class"
*/

class basket {
 var $items;
 var $empty;

 function basket()
 {
  global $cart;
  if(isset($cart))
  {
   $this->items=unserialize(stripslashes($cart));
   if ( gettype($this->items) == "array" )
   {
    $this->empty=false;
   }
   else
    $this->empty=true;
  }
  else
   $this->empty=true;
}

function additem($id, $name, $count, $prix)
{
 if ($this->items[$id][1] > 0 )
 {
  $this->items[$id][1]+=$count;
 }
 else
 {
  $this->items[$id][0]=$name;
  $this->items[$id][1]=$count;
  $this->items[$id][2]=$prix;
  $this->items[$id][3]=stripslashes($name);
 }
 setcookie("cart",serialize($this->items),0,"/");
 $this->empty=false;
}

function removeitem($id) {
 if(!$this->empty)
 while(list($x,$y)=each($this->items)){
  if($x!=$id) $tmp[$x]=$y;
 }
 $this->items=$tmp;
 setcookie("cart",serialize($this->items),0,"/");
 if(count($this->items)==0) $this->empty=true;
}

function resetArray($basket)
{
 reset($basket->items);
}

function countItems($basket)
{
 if(!$basket->empty)
 {
  while ( list($x,$y,) = each($basket->items) )
  {
   $ant++;
  }
 }
 return $ant;
}
function sumItems($basket)
{
 if(!$basket->empty)
 {
  while ( list($x,$y,) = each($basket->items) )
  {
   $ant = $ant + $y[1];
  }
 }
 return $ant;
}
function printItems($b)
{
 if(!$b->empty)
 {
  while ( list($x,$y,) = each($b->items) )
  {
   echo "$x     ".$y[0]."   ".$y[1]."  <a
href=\"$PHP_SELF?action=R&id=$x\">Remove</a><br>";
  }
