                ### 概述 目的是能夠存儲在應用程序中經常使用的對象實例,通常會使用只有靜態方法的抽象類來實現(或使用單例模式)。需要注意的是這里可能會引入全局的狀態,我們需要使用依賴注入來避免它。 ### 實例 ~~~ abstract class Registry{ const LOGGER = 'logger'; private static $storeValues = []; private static $allowKeys = [ self::LOGGER, ]; public static function set(string $key, $value) { if(!in_array($key, self::$allowKeys)){ //TODO,拋異常 } self::$storeValues[$key] = $value; return true; } public static function get(string $key) { if(!in_array($key, self::$allowKeys) || !isset(self::$storeValues[$key])){ //TODO, 拋異常 } return self::$storeValues[$key]; } } ~~~
