php 单例调用

Question

1.今天写了一个redis单例模式类，使用自定义方法调用时，奇怪的是调用两次只有一次生效，各位大佬帮忙瞅瞅呗..代码如下：调用代码： hook('redis_plugin', 'joinQueue', ['key' => 'leo', 'value' => ['测试hook']], 1); hook('redis_plugin', 'popQueue', ['key' => 'leo'], 1); hook方法代码： function hook($class, $function , $params = null, $hookType = 0) { $obj = \eoc\library\Hook::getInstance(); $obj->runHook($class, $function, $hookType, $params); } hook类代码： <?php namespace eoc\library; class Hook { private static $instance; /** * @var string hook文件存放目录 */ protected static $hook; //防止类被克隆 private function __clone() { trigger_error('Clone is not allow!',E_USER_ERROR); } //防止类重复实例化 public static function getInstance() { if (!(self::$instance instanceof self)) { self::$instance = new self; } return self::$instance; } /** * @param $class * @param $function * @param null $params 运行插件 * @param int 插件模式 0 工厂模式 1单例模式 */ public function runHook($class, $function, $hookType = 0, $params = null) { //设置hook类存放目录 $hookPath = APP_PATH . DIRECTORY_SEPARATOR . get_config('plugin_dir') . DIRECTORY_SEPARATOR; //设置后缀 $postfix = '.class.php'; $result = include($hookPath . $class . DIRECTORY_SEPARATOR . $class . $postfix); if (!$result) { setErrorInfo($class . '插件不存在'); } switch ($hookType) { case 0: $object = new $class(); $object->$function($params); break; case 1: //$object = $class::getInstance(); dump($params); // $object::$function($params); break; default: # code... break; } } }

Answer 1

多谢各位大佬的指点，已经解决了把include 替换为require_once就好了

Answer 2

你这也叫单例
runHook hook 也是个静态方法

$obj = \eoc\library\Hook::getInstance();
$obj::runHook($class, $function, $hookType, $params);

你来告诉我，这各下面有什么区别

\eoc\library\Hook::runHook($class, $function, $hookType, $params);
