Introduction:
When you learn PHP, MVC (Model-View-Controller) helps a lot by dividing the app into three parts, making everything more organized and easy to manage. By creating your own MVC framework, you can see how larger PHP frameworks work and learn to build your own solutions.
A PHP Course in Noida will give you hands-on experience with these ideas, teaching you how to create clean and well-organized applications.
What is MVC?
MVC splits your application into three parts:
- Model: This part handles the data and communicates with the database.
- View: This part is what the user sees and uses to interact with the application.
- Controller: This part handles the logic.
These parts separate your application, making it easier to manage and making fixing issues simpler.
Setting Up the Project:
Create a Project Directory:Begin by setting up a new folder for your project. Inside this folder, organize it like this:
The Front Controller (index.php): Inside the /public folder, create an index.php file. This file will act as the front controller, where all requests are routed. It will initialize the app and load the necessary classes.
<?php
// Autoloading classes
require_once '../core/Router.php';
require_once '../core/Controller.php';
require_once '../core/Model.php';
// Initialize Router
$router = new Router();
$router->routeRequest();
Router (Router.php): The router takes incoming requests and decides which controller should handle them.
<?php
class Router {
public function routeRequest() {
// Assuming the URL structure is like /controller/method/param
$url = isset($_GET['url']) ? rtrim($_GET['url'], '/') : 'home/index';
$url = explode('/', $url);
// Define controller and method
$controller = ucfirst($url[0]) . 'Controller';
$method = isset($url[1]) ? $url[1] : 'index';
// Load controller
require_once '../app/controllers/' . $controller . '.php';
$controller = new $controller();
// Call method
if (method_exists($controller, $method)) {
call_user_func_array([$controller, $method], array_slice($url, 2));
} else {
echo "Method not found!";
}
}
}
Controller (Controller.php): The controller receives user input and updates the model and view. A base controller class is created to ensure all controllers inherit common functionality.
<?php
class Controller {
// Base controller with common methods for all controllers
public function view($view, $data = []) {
extract($data);
require_once '../app/views/' . $view . '.php';
}
}
Model (Model.php): We will create a basic model class for database interaction.
<?php
class Model {
protected $db;
public function __construct() {
$this->db = new mysqli('localhost', 'root', '', 'test_db');
if ($this->db->connect_error) {
die('Connection failed: ' . $this->db->connect_error);
}
}
// Example method for retrieving data
public function getData($table) {
$query = "SELECT * FROM $table";
$result = $this->db->query($query);
return $result->fetch_all(MYSQLI_ASSOC);
}
}
View (Views Directory): The view is responsible for displaying data. A simple example could be a view file that displays the data passed by the controller.
<!-- Example view file: home/index.php -->
<h1>Welcome to My Custom MVC Framework</h1>
<ul>
<?php foreach ($data as $item): ?>
<li><?php echo $item['name']; ?></li>
<?php endforeach; ?>
</ul>
.htaccess: To make clean URLs, use .htaccess for URL rewriting.
RewriteEngine On
RewriteCond %{REQUEST_FILENAME} !-f
RewriteRule ^(.*)$ /public/index.php?url=$1 [QSA,L]
