PHP實現路由映射到指定控制器，php路由映射控制器

PHP實現路由映射到指定控制器，php路由映射控制器

自定義路由的功能，指定到pathinfo的url上,再次升級之前的腳本 

SimpleLoader.php

<?php
class SimpleLoader{
 public static function run($rules=array()){
 header("content-type:text/html;charset=utf-8");
 self::register();
 self::commandLine();
 self::router($rules);
 self::pathInfo();
 }
 //自動加載
 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; 
 }
 //命令行模式
 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;
  }
 }
 }
 //路由模式
 public static function router($rules){
 if(isset($_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處理
 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;
  }
  }
 }
 $_GET['m']=!empty($_GET['m']) ? ucfirst($_GET['m']) : 'Index';
 $_GET['c']=!empty($_GET['c']) ? ucfirst($_GET['c']) : 'Index';
 $_GET['a']=!empty($_GET['a']) ? $_GET['a'] : 'index';
 $class="\\Controller\\{$_GET['m']}\\{$_GET['c']}";
 $controller=new $class;
 if(method_exists($controller, $_GET['a'])){
  $controller=new $class;
  $controller->$_GET['a']();
 }else{
  header("HTTP/1.1 404 Not Found");
  echo "404";
 }
 }
 //致命錯誤回調
 public static function shutdownCallback(){
 $e=error_get_last();
 if(!$e) return;
 self::myErrorHandler($e['type'],'<font color="red">Fatal Error</font> '.$e['message'],$e['file'],$e['line']);
 }
 //錯誤處理
 protected static function myErrorHandler($errno,$errstr,$errfile,$errline){
 list($micseconds,$seconds)=explode(" ",microtime());
 $micseconds=round($micseconds*1000);
 $micseconds=strlen($micseconds)==1 ? '0'.$micseconds : $micseconds;
 if(php_sapi_name()=="cli"){
  $break="\r\n";
 }else{
  $break="<br/>";
 }
 $mes="[".date("Y-m-d H:i:s",$seconds).":{$micseconds}] ".$errfile." ".$errline." line ".$errstr.$break;
 echo $mes; 
 }
 //注冊
 public static function register(){
 error_reporting(0);
 set_error_handler(function($errno,$errstr,$errfile,$errline){
  self::myErrorHandler($errno,$errstr,$errfile,$errline);
 });
 register_shutdown_function(function(){
  self::shutdownCallback();
 });
 spl_autoload_register("self::loadClass");
 }
} 

如何使用
index.php 

<?php
//路由映射
$rules=array(
 '^user$'=>'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); 

控制器啥樣
\Controller\User\User.php

<?php
namespace Controller\User;

class User{
 public function getUserById(){
 echo "用戶信息id {$_GET['id']} 的信息";
 }
 public function getUserList(){
 echo "用戶列表";
 }
 public function getUserArticle(){
 echo "用戶id {$_GET['uid']} 的文章列表";
 }
} 

效果呢：
