本文實(shí)例講述了php利用反射實(shí)現(xiàn)插件機(jī)制的方法。分享給大家供大家參考。具體實(shí)現(xiàn)方法如下：

代碼如下:

<?php

/**

* @name PHP反射API--利用反射技術(shù)實(shí)現(xiàn)的插件系統(tǒng)架構(gòu)

*/

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);

希望本文所述對(duì)大家的php程序設(shè)計(jì)有所幫助。
