PHP MVC Class loaded locally but not when uploaded to host - php

Question

I have created the MVC directory structure and started with writing an "App" class.
Everything works well on the local machine using WAMP. But it fails when uploaded to the hosting server.
So, I compared PHP settings between host and local, all looks good, everything matches version etc. I checked paths etc.
Here is my PRIVATE directory structure:
This is the PUBLIC area
This is the index.php file:
<?php
require_once '../httpd.private/init.php';
require_once '../httpd.private/core/App.php';
$app = new App;
?>
Which loads the INIT.PHP variables:
<?php
// Define path constants
define("DS", DIRECTORY_SEPARATOR);
define("ROOT", getcwd() . DS);
define("APP_PATH", ROOT . '../httpd.private' . DS);
define("VIEW_PATH", ROOT . "views" . DS);
define("MODEL_PATH", APP_PATH . "models" . DS);
define("DATA", APP_PATH . "data" . DS);
define("CORE_PATH", APP_PATH . "core" . DS);
define("CONTROLLER_PATH", APP_PATH . "controllers" . DS);
define('SEC_PATH', APP_PATH . "sec" . DS);
define("UPLOAD_PATH", APP_PATH . "uploads" . DS);
define('FILE_ENCRYPTION_BLOCKS', 10000);
$modules = [ROOT, APP_PATH, VIEW_PATH, MODEL_PATH, DATA, CORE_PATH, CONTROLLER_PATH, SEC_PATH];
set_include_path(get_include_path(). PATH_SEPARATOR . implode(PATH_SEPARATOR,$modules));
spl_autoload_register('spl_autoload', false);
?>
After the init file the App.php kicks in:
<?php
class App
{
protected $controller = 'homeController';
protected $method = 'index';
protected $params = [];
public function __construct()
{
$this->parseUrl();
if (file_exists(CONTROLLER_PATH . $this->controller . '.php'))
{
$this->controller = new $this->controller;
if (method_exists($this->controller, $this->method))
{
call_user_func_array([$this->controller, $this->method], $this->params);
} else {
header("Location: /home/index");
}
} else {
header("Location: /home/index");
}
exit();
}
public function parseUrl()
{
if (isset($_GET['url'])){
$url = explode('/', filter_var(rtrim($_GET['url'], '/'), FILTER_SANITIZE_URL));
$this->controller = isset($url[0]) ? $url[0] . 'Controller' : 'homeController';
$this->method = isset($url[1]) ? $url[1] :'index';
unset($url[0], $url[1]);
$this->params = !empty($url) ? array_values($url) : [];
}
}
}
?>
The ERROR:
Fatal error: Uncaught Error: Class 'homeController' not found in
/customers/2/e/9/something.com/httpd.private/core/App.php:15
Stack trace: #0 /customers/2/e/9/something.com/httpd.www/index.php(5): App->__construct() #1 {main} thrown in /customers/2/e/9/something.com/httpd.private/core/App.php on line 15
This is line 15 that is mentioned in the error:
$this->controller = new $this->controller;
And here is the controller.php file:
<?php
class Controller
{
protected $view;
protected $model;
public function __construct()
{
/* echo "This is the Class: " . __CLASS__ . "<br>";
echo "And this is the Method: " . __METHOD__ . "<br>";
die(); */
}
public function view($viewName, $data = [])
{
$this->view = new View($viewName, $data);
return $this->view;
}
public function model($modelName, $data = [])
{
if (file_exists(MODEL_PATH . $modelName . 'Model' . '.php')){
require MODEL_PATH . $modelName . 'Model' . '.php';
$this->model = new $modelName;
}
}
}
?>
How can I correct the error and perhaps better improve the code?
I am aware that I could start with using composer and other frameworks, but that will not help my homework.

Answer 1

I don't see any line where you include your controller file.
Before the instantiation of your controller, you need to require the script.
(You have done that with your model)
