When should a static method be used in a Factory pattern in PHP to return an object of a class?

A static method should be used in a Factory pattern in PHP to return an object of a class when you want to create instances of objects without directly calling the constructor. This allows for centralized creation logic and can help with code organization and maintenance. By using a static method in the Factory pattern, you can encapsulate the object creation process and provide a consistent way to instantiate objects. 

<?php

class Car {
    public $brand;

    public function __construct($brand) {
        $this->brand = $brand;
    }
}

class CarFactory {
    public static function createCar($brand) {
        return new Car($brand);
    }
}

$car = CarFactory::createCar('Toyota');
echo $car->brand; // Output: Toyota

?>
