[PHP] maps routes to a specified controller and php routes

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. "/". $ class. ". php "; if (! File_exists ($ class) {header ("HTTP/1.1 404 Not Found");} require_once $ class;} // command line mode public static function commandLine () {if (php_sapi_name () = "cli") {$ _ SERVER ['path _ info'] = ""; foreach ($ _ SERVER ['argv'] as $ k => $ v) {if ($ k = 0) continue; $ _ SERVER ['path _ info']. = "/". $ v ;}}// public static function router ($ rules) in routing mode {if (isset ($ _ SERVER ['path _ info']) &! Empty ($ rules) {$ pathInfo = ltrim ($ _ SERVER ['path _ info'], "/"); foreach ($ rules as $ k => $ v) {$ reg = "/". $ k. "/I"; if (preg_match ($ reg, $ pathInfo) {$ res = preg_replace ($ reg, $ v, $ pathInfo ); $ _ SERVER ['path _ info'] = '/'. $ res ;}}// pathinfo public static function pathInfo () {if (isset ($ _ SERVER ['path _ info']) {$ pathinfo = array_filter (explode ("/", $ _ SERVER ['path _ info']); for ($ I = 1; $ I <= count ($ pathinfo); $ I ++) {$ key = Isset ($ pathinfo [$ I])? $ Pathinfo [$ I]: ''; $ value = isset ($ pathinfo [$ I + 1])? $ Pathinfo [$ I + 1]: ""; switch ($ I) {case 1: $ _ GET ['M'] = ucfirst ($ key); break; case 2: $ _ GET ['C'] = ucfirst ($ key); break; case 3: $ _ GET ['a'] = $ key; break; default: if ($ I> 3) {if ($ I % 2 = 0) {$ _ GET [$ key] = $ value ;}} break ;}}} $ _ GET ['M'] =!

"line ". $ errstr. $ break; echo $ mes;} // register public static function register () {error_reporting (0); set_error_handler (function ($ errno, $ errstr, $ errfile, $ errline) {self: myErrorHandler ($ errno, $ errstr, $ errfile, $ errline) ;}); register_shutdown_function (function () {self: shutdownCallback ();}); spl_autoload_register ("self: loadClass ");}}

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 ";}}
