Kohana Cache

The default cache group is loaded based on the Cache::$default setting. It is set to the file driver as standard, however this can be changed within 
the /application/boostrap.php file
// Change the default cache driver to memcache
Cache::$default = 'memcache';

// Load the memcache cache driver using default setting
$memcache = Cache::instance();

　　

动态切换缓存方式为file

$key = 'AjSR/piQT24JaYEgh6V9tA==';
$data = array('id'=>1, 'name'=>'liuchao');
Cache::instance("file")->set($key, $data, 60);
print_r(Cache::instance("file")->get($key));
//Cache::instance("file")->set($key, $data, (CFG_DEBUG?-1:60));
