php利用反射实现插件机制的方法

本文实例讲述了php利用反射实现插件机制的方法。分享给大家供大家参考。具体实现方法如下：

复制代码 代码如下:<?php/** * @name    PHP反射API--利用反射技术实现的插件系统架构 */   interface Iplugin{       public static function getName();   }   function findPlugins(){       $plugins = array();       foreach (get_declared_classes() as $class){           $reflectionClass = new ReflectionClass($class);           if ($reflectionClass->implementsInterface("Iplugin")) {               $plugins[] = $reflectionClass;           }       }       return $plugins;   }   function computeMenu(){       $menu = array();       foreach (findPlugins() as $plugin){           if ($plugin->hasMethod("getMenuItems")) {               $reflectionMethod = $plugin->getMethod("getMenuItems");               if ($reflectionMethod->isStatic()) {                   $items = $reflectionMethod->invoke(null);               } else {                   $pluginInstance = $plugin->newInstance();                   $items = $reflectionMethod->invoke($pluginInstance);               }               $menu = array_merge($menu,$items);           }       }       return $menu;   }   function computeArticles(){       $articles = array();       foreach (findPlugins() as $plugin){           if ($plugin->hasMethod("getArticles")) {               $reflectionMethod = $plugin->getMethod("getArticles");               if ($reflectionMethod->isStatic()) {                   $items = $reflectionMethod->invoke(null);               } else {                   $pluginInstance = $plugin->newInstance();                   $items = $reflectionMethod->invoke($pluginInstance);               }               $articles = array_merge($articles,$items);           }       }       return $articles;   }   class MycoolPugin implements Iplugin {       public static function getName(){           return "MycoolPlugin";       }       public static function getMenuItems(){           return array(array("description"=>"MycoolPlugin","link"=>"/MyCoolPlugin"));       }       public static function getArticles(){           return array(array("path"=>"/MycoolPlugin","title"=>"This is a really cool article","text"=> "xxxxxxxxx" ));       }   }$menu = computeMenu();   $articles    = computeArticles();   print_r($menu);   print_r($articles);

希望本文所述对大家的php程序设计有所帮助。
