How can PHP classes be structured to handle multiple data sources for weather interpolation efficiently?

To handle multiple data sources for weather interpolation efficiently, PHP classes can be structured using a strategy pattern. This pattern allows for interchangeable algorithms or data sources to be used dynamically at runtime. By creating separate classes for each data source and implementing a common interface, the code can easily switch between different sources without impacting the main logic of the application. 

interface WeatherSource {
    public function getTemperature($latitude, $longitude);
    public function getHumidity($latitude, $longitude);
}

class WeatherService {
    private $weatherSource;

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

    public function getWeatherData($latitude, $longitude) {
        $temperature = $this->weatherSource->getTemperature($latitude, $longitude);
        $humidity = $this->weatherSource->getHumidity($latitude, $longitude);

        return ['temperature' => $temperature, 'humidity' => $humidity];
    }
}

class OpenWeatherMap implements WeatherSource {
    public function getTemperature($latitude, $longitude) {
        // Implementation for fetching temperature from OpenWeatherMap API
    }

    public function getHumidity($latitude, $longitude) {
        // Implementation for fetching humidity from OpenWeatherMap API
    }
}

class WeatherUnderground implements WeatherSource {
    public function getTemperature($latitude, $longitude) {
        // Implementation for fetching temperature from WeatherUnderground API
    }

    public function getHumidity($latitude, $longitude) {
        // Implementation for fetching humidity from WeatherUnderground API
    }
}

// Example usage
$weatherService = new WeatherService(new OpenWeatherMap());
$data = $weatherService->getWeatherData(37.7749, -122.4194);
