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)
    }
}
