PHP 클래스 Prado\Caching\TAPCCache

TAPCCache implements a cache application module based on {@link http://www.php.net/apc APC}. By definition, cache does not ensure the existence of a value even if it never expires. Cache is not meant to be an persistent storage. To use this module, the APC PHP extension must be loaded and set in the php.ini file the following:


apc.cache_by_default=0

Some usage examples of TAPCCache are as follows,


$cache=new TAPCCache;  // TAPCCache may also be loaded as a Prado application module
$cache->init(null);
$cache->add('object',$object);
$object2=$cache->get('object');

If loaded, TAPCCache will register itself with {@link TApplication} as the cache module. It can be accessed via {@link TApplication::getCache()}. TAPCCache may be configured in application configuration file as follows
