MVC (Model, View, Controller) architectural pattern.

Application of the MVC architectural template (model, view, controller)... Sample code  

The MVC design pattern separates application data, user interface, and control logic into three separate components Model, View, and Controller, so that each component can be modified independently... This allows you to simplify the code of a large application, make it understandable and structured, facilitate maintenance, testing, and reuse of elements!

index.php (Front controller)

// Error settings


// Connecting system files
define('ROOT', dirname(__FILE__));

// Calling Router
$router = new Router(); 

AddDefaultCharset utf-8
#ErrorDocument 404 /
RewriteEngine on
RewriteBase /

RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_FILENAME} !-d

RewriteRule ^(.*)$ index.php
Autoload.php (Automatic class connection function)

function my_autoloader($class_name) 
 // An array of folders in which the necessary classes can be located
    $array_paths = array(
 // We are looking through an array of folders
    foreach ($array_paths as $path) {

 // Formation of the name and path to the file with the class
        $path = ROOT . $path . $class_name . '.php';

 // If such a file exists, we connect it
        if (is_file($path)) {
            include_once $path;
Router.php (Class for working with routes)

class Router
     /** array of routes @var array*/
    private $routes;
     /** The constructor reads and remembers routes*/
    public function __construct()
     // Path to the file with routes
        $routesPath = ROOT . '/config/routes.php';
     // Getting routes from a file
        $this->routes = include($routesPath);
     /** Returns the query string*/
    private function getURI()
        if (!empty($_SERVER['REQUEST_URI'])) {
            return trim($_SERVER['REQUEST_URI'], '/');
     /** Method for processing the request*/
    public function run()
     // Getting the query string
        $uri = $this->getURI();
     // We check the presence of such a request in the array of routes (routes.php)
        foreach ($this->routes as $uriPattern => $path) {
     // Comparing $uriPattern and $uri
            if (preg_match("~$uriPattern~", $uri)) {
     // We get the inner path from the outer one according to the rule (regular expression)
                $internalRoute = preg_replace("~$uriPattern~", $path, $uri);
     // We define the controller, action, and request parameters
                $segments = explode('/', $internalRoute);
     // We get the controller name
                $controllerName = array_shift($segments) . 'Controller';
                $controllerName = ucfirst($controllerName);
     // We define the action
                $actionName = 'action' . ucfirst(array_shift($segments));
                $parameters = $segments;
     // We are connecting the controller class file
                $controllerFile = ROOT . '/controllers/' .
                $controllerName . '.php';
                if (file_exists($controllerFile)) {
     // We are creating a controller object
                $controllerObject = new $controllerName;
     /* We call the necessary method ($actionName) for a certain class ($controllerObject)
      * with the specified parameters ($parameters) 
                $result = call_user_func_array(array($controllerObject, $actionName), $parameters);
     // If the controller method (action) is successfully called, shut down the router
                if ($result != null) {
routes.php (example of an array with routes)

return array(
/** Here we write routes (!!! using regular expressions)...
 * Examples:
 * 'confirm/([0-9a-z]+)' => 'user/confirm_email/$1',
 * 'news/update/([0-9]+)/([0-9]+)' => 'news/update_news/$1/$2',

// Route for the main page of the site
'index.php' => 'site/index', // actionIndex в SiteController
'' => 'site/index', // actionIndex в SiteController
SiteController.php (example of a controller)

class SiteController
 * Action for the main page of the site
	public function actionIndex()
	// Getting data from the model
	$data = Site::getData();
	// Connecting the view
	require_once(ROOT . '/views/site/index.php');
	return true;
The model interacts with the database. Receives data and performs the necessary actions with it.

 * The Site class is a model for SiteController
class Site
public static function getData()
      // connecting to the database 
      // executing a database query
      // getting and returning results
Here is an example of the implementation of an architectural MVC template in the PHP programming language... Be sure to use a software development methodology that prevents the introduction of vulnerabilities, provides resistance to malware and unauthorized access!
