Zend Namespace - Check if Session Exists

问题:

All,

I am using Zend Framework and Zend_Session to do global session management for my application. I plan to clear all sessions on logout and hence am using the following code:

if($this->sessionExists()) {     $this->destroy(); } 

But it seems like it's not doing a good job.. I am getting an error:

    PHP Warning:  session_destroy() [<a href='function.session-destroy'> function.session-destroy</a>]: Trying to destroy uninitialized session  

How can I get rid of this error? Is there an alternative to sessionExists()?

回答1:

This seems to do the trick..

if($this->isStarted()) {     if($this->sessionExists())     {         $this->namespaceUnset("default");         $this->forgetMe();     } }

Not really answers your question about the error, but is beneficial for the question:

$nsName = 'MyNamespace'; if (Zend_Session::namespaceIsset($nsName)) {   echo $nsName.' exists'; }
