XML到PHP的变量

Question

I have a problem with my xml-php-script. XML doc: http://www.yr.no/place/Sweden/Stockholm/Stockholm/forecast.xml

$xmlstr = "http://www.yr.no/place/Sweden/Stockholm/Stockholm/forecast.xml";

//$vader = new SimpleXMLElement($xmlstr);
$vader = simplexml_load_file($xmlstr);

foreach ($vader->forecast->tabular->time->temperature as $temp) {
   echo $temp->temperature, ' ', $temp->windSpeed, PHP_EOL;
}

I want temperature in a variable named: $temp

Answer 1

There are multiple <time>s, so you can loop those. Also, the temperature and windSpeed are in attributes.

foreach ($vader->forecast->tabular->time as $time) {
   echo $time->temperature->attributes()->value, ' ', $time->windSpeed->attributes()->mps, PHP_EOL;

   // or store temperature in a variable?
   // $temp = $time->temperature;
   // echo $temp->attributes()->value; // 14
   // echo $temp->attributes()->unit; // celcius
}

Or to access just the first <time>:

echo $vader->forecast->tabular->time[0]->temperature->attributes()->value;
echo $vader->forecast->tabular->time[0]->windSpeed->attributes()->mps;
