What are some best practices for handling Request data in PHP when working with Factory classes?

When working with Factory classes in PHP, it is important to properly handle Request data to ensure secure and efficient processing. One best practice is to validate and sanitize input data before passing it to the Factory class to prevent injection attacks or unexpected behavior. Additionally, using type hinting and parameter validation can help enforce the correct data types and formats for the Factory class methods.

// Example of handling Request data in PHP when working with Factory classes

class Factory {
    public function createObject(string $name, int $quantity) {
        // Factory logic here
    }
}

// Validate and sanitize input data before passing to the Factory class
$name = filter_var($_POST['name'], FILTER_SANITIZE_STRING);
$quantity = filter_var($_POST['quantity'], FILTER_VALIDATE_INT);

$factory = new Factory();
$factory->createObject($name, $quantity);
