سلام علی آقا خیر درست نشد.

@fghayyem
شما قبل از اینکه autoload رو require کنید از کلاس HomeControler استفاده کردید، فایل index.php شما اگر اون اولی باشه که فرستادید ( اگر نه فایل index.php که همه ی ریکوست ها به پروژه شما به اون میخوره رو بفرستید )

سلام آقا بهزاد

@fghayyem
ببینید اگر شما داخل اون فایل header.php که require کردید autoload رو require نکرده باشید پس در کل قبل از اینکه از مفهوم namespace استفاده کنید autoload رو require نکردید و طبیعیه این ارور رو بگیرید .

<?php
در این قسمت و قبل از اینکه از مفهوم namespace استفاده کنید باید autoload require بشه
use App\Controller\HomeController;
require('./templates/header.php');

$homeController=new \App\Controller\HomeController();
var_dump($homeController);
?>

لطفا composer.json رو بفرستید

تنها مشکلی که شما دارید عدم دقت هست نه بیشتر.
اسم فایلتون به اشتباه HomeControler.php که با تغییرش به HomeController.php مشکلتون حل میشه
