php寫的一個緩衝介面demo,相容redis和memcache

/** * Factory 方法模式 * ------------- * @author zhangqian * @version v1.0 */ //緩衝介面 interface cache { public function init($conf); public function setVal($key , $val); public function getVal($key); public function delVal($key); public function autoIncreament($key); } //mem class mymemCache implements cache { //mymem串連 public function init($conf) { echo '初始化mymem'; } public function setVal($key , $val) { echo 'mem設定值'; } public function getVal($key) { echo 'mem擷取值'; } public function delVal($key) { echo 'mem刪除值'; } public function autoIncreament($key) { echo 'mem自增'; } } //redis class redisCache implements cache { //redis串連 public function init($arr) { echo '初始化redis'; } public function setVal($key , $val) { echo 'redis設定值'; } public function getVal($key) { echo 'redis擷取值'; } public function delVal($key) { echo 'redis刪除值'; } public function autoIncreament($key) { echo 'redis自增'; } } class cacheFactory { private static $obj; private static $type; private static $conf; private static $allowtype = array('mymem','redis'); private static function getConfig() { //include_once('config.php');載入設定檔 擷取緩衝的類型 及緩衝的配置參數 global $_SC; self::$type = $_SC['cachetype'];//做空值的判斷 self::$conf = $_SC['cacheconf'];//做空值的判斷 } //外部調用建立緩衝對象 public static function CreateOperation(){ self::getConfig(); try { $error = '未知的緩衝類型'; if(in_array(self::$type , self::$allowtype)) { $type = self::$type.'Cache'; self::$obj = new $type; self::$obj->init(self::$conf);//串連 } else throw new Exception($error); } catch (Exception $e) { echo 'Caught exception: ', $e->getMessage(), "\n"; exit; } return self::$obj; } } $_SC = array(); $_SC['cachetype'] = 'redis';//mymem $_SC['cacheconf'] = array(); $cache = cacheFactory::CreateOperation(); $cache->setVal('a',1); echo ' '; $a = $cache->getVal('a'); echo ' '; $cache->delVal('a'); ?> 複製代碼
