How PHP uses reflection to implement plug-in mechanisms

This article mainly introduces PHP using reflection to implement plug-in mechanism, involving the PHP reflection mechanism and plug-in implementation skills, the need for friends can refer to the following

In this paper, we explain how PHP uses reflection to implement plug-in mechanisms. The specific implementation method is as follows

The code is as follows:

<?php/** * @name PHP Reflection api--Plug-in system architecture using reflection technology */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 (' description ' = ' mycoolplugin ', ' link ' = '       /mycoolplugin ')); } public static function Getarticles () {return Array (The array (' path ' = '/mycoolplugin ', ' title ' = ' = ' This is a really cool article ', ' text ' = ' xxxxxxxxx ');   }} $menu = Computemenu ();   $articles = Computearticles ();   Print_r ($menu); Print_r ($articles);
