How can functions and classes be used in PHP to improve code organization and maintainability?

Using functions and classes in PHP can improve code organization and maintainability by allowing you to encapsulate related functionality into reusable modules. Functions can be used to group together a set of related operations, while classes can be used to define objects that contain both data and methods to operate on that data. This approach helps to break down complex tasks into smaller, more manageable pieces, making your code easier to understand, debug, and maintain. 

// Example of using functions and classes for improved code organization and maintainability

// Define a class to represent a car
class Car {
    public $make;
    public $model;
    
    public function __construct($make, $model) {
        $this->make = $make;
        $this->model = $model;
    }
    
    public function displayInfo() {
        echo "This car is a {$this->make} {$this->model}.";
    }
}

// Create a new instance of the Car class
$myCar = new Car('Toyota', 'Corolla');

// Call the displayInfo method to show information about the car
$myCar->displayInfo();
