Question

我创建了会话数组，我在那里放置了值，如下面的代码

$ar= array(
            'product_id' => $this->input->post('productid'),
            'qty'=> 1,

            );
            //creating products session array for the first time
            $this->session->set_userdata('products',$ar);

现在，如何检索这些信息？我需要将新信息推送到现有会话数组。怎么做？

只需获取它并以数组形式访问它：

$products = $this->session->userdata('products');

$id = $products['product_id'];
$qty = $products['qty'];

推动类似：

$products['new_info'] = 'something'; // provided you already fetched the array
$this->session->set_userdata('products', $products);
// now the 'products' session variable contains 'product_id', 'qty' and 'new_info'

从codeigniter中的会话数组中检索信息
