PHP implementation route map to specified controller _php tips

Customize the routing function, specify the URL to PathInfo, and upgrade the script before

simpleloader.php

How to use
index.php

<?php
//Routing mapping
$rules =array (
 ' ^user$ ' => ' user/user/getuserlist ',
 ' ^user\/' (\d+) $ ' => ' user/ User/getuserbyid/id/$1 ',
 ' ^user\/(\d+) \/article$ ' => ' user/user/getuserarticle/uid/$1 '
);
Require_once "simpleloader.php";
Simpleloader::run ($rules); 

Controller What kind of
\controller\user\user.php

<?php
namespace Controller\user;

Class user{public
 function Getuserbyid () {
 echo user information id {$_get[' id '} information ';
 }
 Public Function Getuserlist () {
 echo "user list";
 }
 List of articles for public function getuserarticle () {
 echo User ID {$_get[' uid '}}
