如何检索magento中的数组值

Question

例如，我需要从此会话中检索一个值。我应该怎么做 ？确切地说，我需要获得“customer_log_id”。

Answer 1

$a['core']['visitor_data']['customer_log_id'] 

Answer 2

看样子，你想检索来自$_SESSION阵列的信息。有两种方法可以做到这一点。作为另一个海报建议，你可以简单地砍出来的$_SESSION超全局正是如此的：

$logId = $_SESSION['core']['visitor_data']['customer_log_id']; 

然而，这是一个黑客位，以避免Magento的框架。 （从“正确性”的角度来看）更好的选择是使用Magento的会话管理。因此，我们有：

// we could also skip a step and just use Mage::getSingleton("core/session")->getVisitorData(), 
// but I wanted to add the datatypes for your reference 
$session = Mage::getSingleton("core/session"); // Mage_Core_Model_Session 
$customerData = $session->getVisitorData(); // array 
$logId = $customerData['customer_log_id']; // int 

希望帮助！
