Zend\Cache\Pattern\CallbackCache¶
Overview¶
The callback cache pattern caches calls of non specific functions and methods given as a callback.
Quick Start¶
For instantiation you can use the PatternFactory
or do it manual:
1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 | use Zend\Cache\PatternFactory;
use Zend\Cache\Pattern\PatternOptions;
// Via the factory:
$callbackCache = PatternFactory::factory('callback', array(
'storage' => 'apc',
'cache_output' => true,
));
// OR, the equivalent manual instantiation:
$callbackCache = new \Zend\Cache\Pattern\CallbackCache();
$callbackCache->setOptions(new PatternOptions(array(
'storage' => 'apc',
'cache_output' => true,
)));
