Rendering views
View rendering is the process where a controller loads a view file and supplies it with data, so the view can generate dynamic output for the user.
To render a view, a controller usually calls a method like render to load the needed view file. It can pass data as variables, which the view uses to show dynamic content.
This keeps the controller responsible for preparing data, while the view focuses only on presentation.
BaseController.php
views/greeting.php
HelloController.php
1234567891011<?php class BaseController { public function render($view, $data = []) { // Extract variables for use in the view extract($data); include __DIR__ . "/views/{$view}.php"; } }
When the controller calls the render method, it passes the view name and an array of data. The extract function turns array keys into variables, making them accessible in the view file. In the example above, the key 'name' becomes the variable $name in greeting.php, allowing the view to display a personalized message.
BaseController.php
views/user_profile.php
UserController.php
12345678910111213<?php class BaseController { public function render($view, $data = []) { // Support passing any associative array as variables if (!empty($data) && is_array($data)) { extract($data, EXTR_SKIP); } include __DIR__ . "/views/{$view}.php"; } }
By using associative arrays to pass data, the render method allows you to send multiple variables to a view at once. This keeps your views flexible and dynamic, because you can change what data the controller provides without modifying the view's structure. It also preserves a clear separation between logic and presentation, making the code easier to maintain and extend.
