问题
Maybe I'm just not seeing it, but is there any other way to access a previously created session namespace, other than calling $_SESSION directly? Besides the fact that I really don't want to do this, the Zend documentation also advises against this:
while $_SESSION is still available in PHP's global namespace, developers should refrain from directly accessing it, so that Zend_Session and Zend_Session_Namespace can most effectively and securely provide its suite of session related functionality.
The Zend_Session_Namespace class doesn't have a static method for getting a namespace, and although the now deprecated namespaceGet method in Zend_Session instructs me to use Zend_Session_Namespace#getIterator, that method is not static.
So that means I need to initialize a new namespace, using the new keyword. The problem is, this doesn't include previously set variables:
$ns = new Zend_Session_Namespace('foo');
$ns->foo = 'bar';
On a subsequent request, this:
print_R(new Zend_Session_Namespace('Foo'));
...prints this:
Zend_Session_Namespace Object
(
[_namespace:protected] => Foo
)
which seems obvious.
So how am I supposed to fetch the previously created namespace, without using $_SESSION['Foo']?
回答1:
The case of your two code examples doesn't match (foo vs. Foo), I'm not sure if that was just a typo or not. Zend_Session_Namespace is just a wrapper for $_SESSION, so all you need to do is create a namespace object with the same key and then all your data should be available.
$ns = new Zend_Session_Namespace('foo');
$ns->foo = 'bar';
and then on another page:
$ns = new Zend_Session_Namespace('foo');
echo $ns->foo; // should output bar
if this doesn't work then there is a problem with your session configuration.
