You can retrieve data in JSON format, and then use json_decode() function to build stdClass object, then you can recursively walk through object's property to convert it into (array) $response as this.

And then use Google Maps API response as an array. You can proceed with no converting to array, and use object of stdClass like this:

$response->DirectionsResponse->route->leg->step->start_location->lat;

To get the correct values you can always var_dump() you response object, and see what you want to get.

Hope, that helps.

Here is the code for usage Google JSON response from Google Translate API... which is much the same, as you need:

if (!is_null($json = json_decode(file_get_contents($url)))
{
    return $json->data->translations[0]->translatedText;
}

That's it...
