php 的路由简介 ?（一个简单的路由模式）

<?php$_SERVER[‘REQUEST_URI‘] = ‘/post/edit/1024?foo=bar‘;$uri = explode(‘/‘, parse_url($_SERVER[‘REQUEST_URI‘], PHP_URL_PATH));var_export($uri);//输出array ( ?0 => ‘‘, ?1 => ‘post‘, //控制器(控制器存在就require) ?2 => ‘edit‘, //方法 ?3 => ‘1024‘, //参数(获取参数foo就用传统的$_GET[‘foo‘]))$class = $uri[1];require ‘controller/‘.$class.‘.php‘; // controller/post.php$object = new $class();$action = $uri[2];$parameter = $uri[3];echo call_user_func_array(array($object, $action), array($parameter)); //调用对象里的方法并传参controller/post.php:class post { ???public function edit($id) { ???????return ‘$‘.__CLASS__.‘->‘.__FUNCTION__.‘(‘.$id.‘)‘; //输出 $post->edit(1024) ???}}
