PHP实现路由映射到指定控制器

自定义路由的功能，指定到pathinfo的url上,再次升级之前的脚本 

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(); } //自动加载 public static function loadClass($class){ $class=str_replace('\\', 'https://www.jb51.net/', $class); $dir=str_replace('\\', 'https://www.jb51.net/', __DIR__); $class=$dir."https://www.jb51.net/".$class.".php"; if(!file_exists($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; $_SERVER['PATH_INFO'].="https://www.jb51.net/".$v; } } } //路由模式 public static function router($rules){ if(isset($_SERVER['PATH_INFO']) && !empty($rules)){ $pathInfo=ltrim($_SERVER['PATH_INFO'],"https://www.jb51.net/"); foreach ($rules as $k=>$v) { $reg="https://www.jb51.net/".$k."/i"; if(preg_match($reg,$pathInfo)){ $res=preg_replace($reg,$v,$pathInfo); $_SERVER['PATH_INFO']='https://www.jb51.net/'.$res; } } } } //pathinfo处理 public static function pathInfo(){ if(isset($_SERVER['PATH_INFO'])){ $pathinfo=array_filter(explode("https://www.jb51.net/", $_SERVER['PATH_INFO'])); for($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"; } } //致命错误回调 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']); } //错误处理 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 $mes; } //注册 public static function register(){ error_reporting(0); set_error_handler(function($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);  

控制器啥样
\Controller\User\User.php

<?php namespace Controller\User; class User{ public function getUserById(){ echo "用户信息id {$_GET['id']} 的信息"; } public function getUserList(){ echo "用户列表"; } public function getUserArticle(){ echo "用户id {$_GET['uid']} 的文章列表"; } }

效果呢：
