如何使用动态调用的控制器动态调用函数？

Question

I'm trying to impove my mini web site by implementing a dynamic router so I did the following

<?php

use App\Controller\Autoloader;
use App\Controller\PostController;
require_once("controller/Autoloader.php");

Autoloader::register(); 


$url = $_SERVER['REQUEST_URI'];

$url = explode('/', $url);
array_shift($url);
$base = $url[0];
$url = $url[1];
$page = "";
$function = "";
$controller = "";
 $urlArray = array(
'base' => $base,
'page' => $page,
'parameters' => array(
    "controller" => $controller,
    "function" => $function
)
 );
 $url = explode("?", $url);
 $urlArray["page"] = $url[0];


 $url = explode("&", $url[1]);

 $urlArray['parameters']['controller'] = str_replace("controller=", "",       $url[0]);
 $urlArray['parameters']['function'] = str_replace("action=", "", $url[1]);

 $controllerName = $urlArray['parameters']['controller'];
 $controller = new $controllerName();

 $controller->$urlArray['paremeters']['function']();

Since my url is cleperduv2/index.php?controller=PostController&action=listPosts

I want to call the function listPosts on the controller PostController.php

( ! ) Fatal error: Class 'PostController' not found in C:\wamp64\www\cleperduv2\index.php on line 40

Looks like it's something with namespacing, Have you tried to call it like this: $namespace = "App\Controller\\"; $controllerName = $namespace . $urlArray['parameters']['controller']; $controller = new $controllerName;

You can drop down the use namespace statement for the PostController and this way ll of your controllers will be required, declared, and instanciated dynamically as you want !
