Php get/iterate 特定会话的值

Question

嗨伙计们我不明白如何在会话中创建用于保存这些不同值的代码。这是单个会话结果的示例：第一个数组包含两种不同的产品第二个数组包含登录用户的名字第三个数组包含登录用户的姓氏

非常感谢。

我已经解决了，感谢您的帮助，我了解了会话的工作原理。

// fist and last name of user
$_SESSION['nome'] = $_POST['nome'];
$_SESSION['cognome'] = $_POST['cognome'];

// here add the article inside the session
$_SESSION['cart'][$_POST['productCode']] = [
'article' => $_POST['productName'],
'price' => $_POST['buyPrice'],
'quantity' => $_POST['num_prodotto']
];

// for add the quantity for the same product 
$_SESSION['cart'][$_POST['productCode']]['quantity']+=$_POST['num_prodotto'];

不需要3个session，用1个session

您的代码可以是这样的：

session_start();
$_SESSION['nome'] = 'nome';
$_SESSION['cognome'] = 'cognome';
// for this case the cart is empty:
$_SESSION['cart'] = [];

// add a product:
$article = 'A-1';
$_SESSION['cart'][$article] = [
    'article' => $article,
    'price' => 100,
    'quantity' => 1,
];

print_r($_SESSION);

// add second product:
$article = 'A-2';
$_SESSION['cart'][$article] = [
    'article' => $article,
    'price' => 100,
    'quantity' => 1,
];

print_r($_SESSION);

// update quantity under article A-1:
$article = 'A-1';
$_SESSION['cart'][$article]['quantity'] += 1;

print_r($_SESSION);
