How can a developer effectively balance learning modular programming concepts with practical application in PHP projects?

To effectively balance learning modular programming concepts with practical application in PHP projects, developers can start by breaking down their projects into smaller, reusable modules that can be easily maintained and tested. They can then focus on implementing design patterns such as MVC (Model-View-Controller) to separate concerns and improve code organization. Finally, developers should continuously practice modular programming principles in their projects to reinforce their understanding and improve their skills. 

// Example of implementing modular programming in PHP using MVC design pattern

// Model - responsible for handling data logic
class User {
    public function getUserById($id) {
        // fetch user data from database
        return $userData;
    }
}

// View - responsible for displaying data
class UserView {
    public function displayUser($userData) {
        // display user data in a formatted way
    }
}

// Controller - responsible for handling user input and interactions
class UserController {
    private $userModel;
    private $userView;

    public function __construct() {
        $this->userModel = new User();
        $this->userView = new UserView();
    }

    public function showUser($userId) {
        $userData = $this->userModel->getUserById($userId);
        $this->userView->displayUser($userData);
    }
}

// Implementation
$controller = new UserController();
$controller->showUser(1);
