[PHP] the implementation of loading different controllers in url pathinfo mode, urlpathinfo

The pathinfo mode and common url mode are implemented by calling different controllers by automatically loading and parsing url parameters.

File structure:

| -- Controller
| -- Index
| -- Index. php

| -- Application. php

Application. php

<?phpclass Application{    public static function main(){        header("content-type:text/html;charset=utf-8");        self::register();        self::router();    }    public static function register(){        spl_autoload_register("self::loadClass");    }    public static function loadClass($class){        $class=str_replace('\\', '/', $class);        $class="./".$class.".php";        require_once $class;            }    public static function router(){        if(isset($_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;        $controller->$_GET['a']();    }}Application::main();
