推荐答案

向php数组问好: http://www.php.net/manual/en/book.array.php :)
基本上代替:

Say hello to php arrays: http://www.php.net/manual/en/book.array.php :)
Basically instead of :

$_SESSION['id'] = 1234;

您将要:

$_SESSION['products'][] = array('id'=>1234, 'quantity'=>10);

然后，您将像

foreach($_SESSION['products'] AS $product){
   echo $product['id'];
}
