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

$v) {
                if($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处理
    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);

    //致命错误回调

控制器啥样
