class Product { private static $price = 10; public static function getPriceStatic() { return self::$price; } } echo Product::getPriceStatic(); // Output: 10In this example, the Product class has a private static property $price set to 10. The getPriceStatic() function returns this static property value when called. Based on this code example, I can determine that this function belongs to a package/library related to e-commerce or product management.
