autoload in the - php classes

Question

It is a scheme that I am inventing since in this project I do not go by framework for being very simple,

Working with MVC in the Framework (Codeigniter),

But I don’t have a separate Model class with loading (only as a file), it’s always an extension of Controller, so I’ll create my controller, give them a name in the boot config and I want the load to load all of these that are in the array, together with the model of each.

What is missing is that it automatically loads the name of the $variable being the name of the Controller in minuscule letter, and the new = Class; instead of the word "Class" I want the name of the file that is the same name as the Controller class.

In short, auto load, but already give the new command to initialize the class, it is giving error.

Code:

<?php
/* ------------------------------------------------------ *
 * Configuração do php
 * ------------------------------------------------------ */
ini_set('display_errors', 1);
/* ------------------------------------------------------ *
 * Configuração inicial do Sistema
 * ------------------------------------------------------ */
$base_url           = 'http://localhost:8081/bitbucket/16.4.2/';
$index_page         = 'index.php';
$charset            = 'ISO-8859-1';
$autoload           = 1;
/* ------------------------------------------------------ *
 * Configuração do autoload
 * ------------------------------------------------------ */
$autoload['Controller']     = array(
  "Cliente",
  "Administrador",
  "Ticket",
  "Notificacao"
);
$autoload['lib']            = array("buscaCep","fup");
/* ------------------------------------------------------ *
 * Carrega a configuração
 * ------------------------------------------------------ */
  spl_autoload_register(function ($nome) {
    global $base_url;
    foreach($autoload['Controler'] as $elemento):
      if ($elemento == $nome):
        $Controller = $base_url."Controller/".$nome.".Controller.php";
        if(is_file($Controller)):
          $Model = $base_url."Model/".$nome.".Model.php";
          if(is_file($Model)):
            include_once("$Model");
          endif;
          include_once("$Controller");
          ${strtolower($nome)} = new {$nome};
        endif;
      endif;
      $x++;
    endforeach;
  });
/* ------------------------------------------------------ *
 * Inicializar Controllers com o comando ''$nomedoobj = new Controller';
 * ------------------------------------------------------ */
//$administrador  = new Administrador();
//$ticket = new Ticket();

foreach($autoload['Controler'] as $elemento):
  ${strtolower($elemento)} = new {$elemento};
endforeach;
?>

Line with error is:

Parse error: syntax error, Unexpected '{' in /home/Andre/public_html/bitbucket/16.4.7/conf.php on line 49

Code:

${strtolower($nome)} = new {$nome};

The name of the file where the class is Controller/Administrator.Controller.php

And here’s the code:

<?php
class Administrador extends AdministradorModel {

    function helloworld(){
        echo "<h1>Hello World</h1>";
    }
}

I imagine the code I typed in line with error would be the theory of how I want it to work, of course, it’s wrong, but how could it be ?
