来自对象php的数据

Question

I have a object that creates simplexml_load_file();

$xmlPoland = simplexml_load_file('http://export.yandex.ru/weather-ng/forecasts/12375.xml');

echo "<pre>";
print_r($xmlPoland);
echo "</pre>";

I need to get the value of the [fact] temperature(-9).

How to make this?

Answer 1

This should work for you:

echo $xmlPoland->fact->temperature;

Output:

-9

If you need it from this part:

[fact] => SimpleXMLElement Object
    (
        [@attributes] => Array
            (
                [source] => forecast
            )

        [observation_time] => 2014-12-29T19:06:19
        [uptime] => 2014-12-29T19:06:19
        [temperature] => -9
        [weather_condition] => SimpleXMLElement Object
            (
                [@attributes] => Array
                    (
                        [code] => mostly-clear
                    )

            )
