How can PHP functions be effectively used to include common elements like menus and headers across multiple pages without sacrificing code readability and maintainability?

Using PHP functions, we can create reusable code snippets for common elements like menus and headers. By creating separate functions for these elements, we can include them in multiple pages without duplicating code. This approach improves code readability and maintainability by centralizing the logic for these elements in one place. 

// Function to include a common header
function includeHeader() {
    include 'header.php';
}

// Function to include a common menu
function includeMenu() {
    include 'menu.php';
}

// Example usage in a webpage
includeHeader();
includeMenu();
// Other page content
