PHP implements route ing to the specified controller and php route ing Controller

The custom routing function is specified to the url of pathinfo and the previous script is upgraded again.

SimpleLoader. php

<? Phpclass SimpleLoader {public static function run ($ rules = array () {header ("content-type: text/html; charset = UTF-8"); self: register (); self: commandLine (); self: router ($ rules); self: pathInfo ();} // automatically load public static function loadClass ($ class) {$ class = str_replace ('\', '/', $ class); $ dir = str_replace ('\', '/', _ DIR __); $ class = $ dir.

How to Use
Index. php

<? Php // route ing $ 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 );

 

What is a controller?
\ Controller \ User. php

<? Phpnamespace Controller \ User; class User {public function getUserById () {echo "User information id {$ _ GET ['id']}";} public function getUserList () {echo "User List";} public function getUserArticle () {echo "User ID {$ _ GET ['uid']}'s article list ";}}
