Add an template file in src/Template/Test/index.ctp and add some HTML.
You cannot echo within the controller. CakePHP sends the variables to the View and you can access it there:
// in your controller do this:
class TestController extends AppController
public function index() {
$message = "Hii";
$this->set(compact('message'));
}
}
Your Tempate file src/Template/Test/index.ctp should look like this:
<?php
echo $message;
?>
