Expire the Zend session if the user remains idle f

Question

I am new to zend and I want to ask how can I expire a user's session namespace's particular key if a user remains idle for 10 minutes. I have a namespace defined in zend session as

 $session = new Zend_Session_Namespace('loginNamespace');

now when the user logs in I set the key loggedIn = 1 in session namespace. Now I want to expire not the whole session if the user remains idle but only that key. how can I do that?

From the documentation, you can expire a key using:

$session->setExpirationSeconds( 600, 'key' );

So, how can you play with that? This way:

// Set "dummy" key with expiration
$session->setExpirationSeconds( 600, 'key' );

// Then, you can check if this key exists
if ( $session->key ) {
    // Just reset the expiration
    $session->setExpirationSeconds( 600, 'key' );
}
else {
    // Delete your other key
}
