sessionphp
请教各位大神，下面PHP代码中"$_SESSION['cart'][$new]"的使用是什么语法？
<code> if($new) { //new item selected if(!isset($_SESSION['cart'])) { $_SESSION['cart'] = array(); $_SESSION['items'] = 0; $_SESSION['total_price'] ='0.00'; } if(isset($_SESSION['cart'][$new])) { $_SESSION['cart'][$new]++; } else { $_SESSION['cart'][$new] = 1; }</code> Statement：
