    There is not one script for all php shopping carts. If you search, you should find a lot of possibilities, but all of them will require customization. ∠°)http://www.shop-script.com/php-shopping-…

    hi there luckily i used php script to create a shopping cart in the past so here is what you should do…. it’s fairly easy so bare with me.
    1. first you need to represent the cart as a string and all your products as integers which are the product ids, like a 1 dimensional array of product ids separated by commas (,).
    2. When you add an item it will look like that
    if ($cart) $cart.=”,”;//if not empty then add a comma
    $cart.=strval($id);//first will be 6 then 6,31 then 6,31,192 and so on
    3. later on when you want to seperate all the items you will need to use the explode() function.
    $items = explode(‘,’,$cart);
    explode() will take each id and put it in a new array called $items and you could print them out:
    foreach ($items as $item)
    {
    echo $item;
    }
    to remove an item you would need to create a new items array, go over all items and if it matches the removed item don’t copy it to the new array.
    to empty the cart just write
    $cart=”";
    Now you will need to store the cart string in a session variable (hope you know what it means, you should if they asked you to create a shopping cart…)
    session_start();
    $_SESSION['cart']=$cart;
    and on a different page just recall it by writing
    session_start();
    $cart=$_SESSION['cart'];
    If you want my complete code then here it is…
    $action=$_GET['action'];
    //you can send an action to the file by creating a link that links to “cart.php?action=ADD&id=123″;
    $cart=$_SESSION['cart'];
    $id=strval($_GET['id']);
    if ($action==”ADD”) {
    if ($cart) $cart.=”,”;
    $cart.=strval($id);
    $_SESSION['cart']=$cart;
    }
    if ($action==”REMOVE”) {
    $items = explode(‘,’,$cart);
    $TimesFound=0;
    $newcart = ”;
    $ItemCount = 0;
    //first count the number of times the specific item appear in cart, in order to remove only the last one so the order of the items won’t change
    foreach ($items as $item) {
    if ($item==$id) $itemCount++;
    }
    foreach ($items as $item) {
    if ($id!=$item) {
    if ($newcart) $newcart.=”,”;
    $newcart.=strval($item);
    }
    if ($id==$item){
    $TimesFound++;
    if ($TimesFound!=$itemCount)
    {
    if ($newcart) $newcart.=”,”;
    $newcart.=strval($item);
    }
    }
    }
    $cart=$newcart;
    $_SESSION['cart']=$cart;
    }
    if ($action==”EMPTY”) {
    $cart=”";
    $c=0;
    $_SESSION['cart']=”";
    }
    Hope this helps…
    let me know if you need more help.
