15.6.1. 插件管理平台


     path = $this->directory.'/';	}	public function autoload(){		$interfaces = scandir($this->directory);		unset($interfaces[0]);		unset($interfaces[1]);		foreach($interfaces as $interface)		{			//load all of the plugins			$file =  $this->path . $interface;			if (@file_exists($file))			{				include_once($file);				$class =  basename($interface, ".php");				if (class_exists($class))				{					$this->$class = new $class($this);					$vars = get_class_vars($class);					$entity['name'] 			= $vars['name'];					$entity['description'] 	= $vars['description'];					$entity['author'] 		= $vars['author'];					$entity['class'] 		= $class;					$entity['methods'] 		= get_class_methods($class);					$this->plugins[$class] = $entity;				}			}		}	}	public function load($plugin){		$file = $this->path . $plugin . '.php';		if (@file_exists($file))		{			include_once($file);			$class = $plugin;			if (class_exists($class))			{				$this->$class = new $class($this);				$vars = get_class_vars($class);				$entity['name'] 			= $vars['name'];				$entity['description'] 	= $vars['description'];				$entity['author'] 		= $vars['author'];				$entity['class'] 		= $class;				$entity['methods'] 		= get_class_methods($class);				$this->plugins[$class] = $entity;			}		}	}	public function show(){		print_r($this->plugins);	}}

15.6.2. 接口定义

15.6.3. 插件


     ';	public static $name = 'Demo';	public static $description = 'Demo Simple';	public function __construct(){	}	public function test(){		echo 'Hello world!!!';	}}
