這篇文章主要介紹了php利用反射實現插件機制的方法,涉及php反射機制與插件的實現技巧,需要的朋友可以參考下
本文實例講述了php利用反射實現插件機制的方法。分享給大家供大家參考。具體實作方法如下:
程式碼如下:
<?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);
