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 (Extra) If I store $timeline->status rather than the whole $timeline object the array is stored but I still get 4 unserialize errors and this error: *Warning*: Home_TimelineController::publicAction() [ home-timelinecontroller.publicaction<http://localhost/home/timeline/home-timelinecontroller.publicaction>]: Node no longer exists in * D:\development\twitter\application\modules\home\controllers\TimelineController.php * on line *53 *( Line 53: if (!($timeline = $cache->load('publicTimeline'))) { )* * -- Ross Masters [EN, GMT+0] Twitter: @rossmasters
