Hi all, I'm relatively new with ZF and completely new to the lists - so I
apologies if this is the wrong list.
I'm trying to cache the Twitter public timeline for 60 seconds, using the
code below:
$frontendOptions = array(
'lifetime' => 60,
'automatic_serialization' => true
);
$backendOptions = array('cache_dir' => APPLICATION_PATH . '/../tmp/');
$cache = Zend_Cache::factory(
'Core',
'File',
$frontendOptions,
$backendOptions);
if (!($timeline = $cache->load('publicTimeline'))) {
$timeline = $this->_twitter->status->publicTimeline();
$cache->save($timeline);
}
print_r($timeline);
This works fine on the first run, but the second and later runs (up till the
cache expires) I get this error:
*Warning*: unserialize()
[function.unserialize<http://localhost/home/timeline/function.unserialize>]:
Node no longer exists in *D:\twitter\library\Zend\Cache\Core.php* on line *278
(x91)*
Zend_Rest_Client_Result Object ( [_sxml:protected] => SimpleXMLElement
Object
*Warning*: print_r()
[function.print-r<http://localhost/home/timeline/function.print-r>]:
Node no longer exists in *
D:\twitter\application\modules\home\controllers\TimelineController.php* on
line *58*
( ) )
I've tried storing a simple array and a small stdClass Object and they work
fine. I had an idea it could be to do with references but when I store an
instance of Zend_Registry in the object that works fine too.
I'm completely at a loss here - I'm practically following the reference
guide examples. If anyone can help I'd be grateful.
Regards,
Ross

If I store $timeline->status rather than the whole $timeline object the
array is stored but I still get 4 unserialize errors and this error:
*Warning*: Home_TimelineController::publicAction() [
home-timelinecontroller.publicaction<http://localhost/home/timeline/home-timelinecontroller.publicaction>]:

$cache->load('publicTimeline'))) { )*
