What is the significance of Separation of Concerns (SoC) in PHP development, and how can it be applied to improve code structure?

Separation of Concerns (SoC) is a design principle in software development that suggests breaking a program into distinct sections, each handling a specific aspect of functionality. In PHP development, applying SoC helps improve code structure by promoting modularity, reusability, and maintainability. This can be achieved by separating different concerns such as presentation logic, business logic, and data access logic into separate components. ``` <?php // Presentation logic class View { public function render($data) { // Render the view } } // Business logic class Controller { public function processRequest($request) { // Process the request } } // Data access logic class Model { public function getData() { // Retrieve data from the database } } // Implementation $view = new View(); $controller = new Controller(); $model = new Model(); $data = $model->getData(); $controller->processRequest($data); $view->render($data); ?> ```
