Question

I just want to read out the google weather api xml with that code but it returns a 500. Any ideas why?

<?php
 $url = "http://www.google.com/ig/api?weather=Moskva&hl=en";
 $xml = simplexml_load_string(utf8_encode(file_get_contents($url)));
 echo $xml->weather->current_conditions->temp_c->attributes()->data;
?>

Answer 1

Separate the lines out and introduce a try / catch block as follows :

try {
  $url = "http://www.google.com/ig/api?weather=Moskva&hl=en";
  $temp1 = file_get_contents($url);
  $temp2 = utf8_encode($temp1);
  $xml = simplexml_load_string($temp2);
  echo $xml->weather->current_conditions->temp_c->attributes()->data;
} catch (Exception $e) {
   echo 'Caught exception: ',  $e->getMessage(), "\n";
}

what happens then ?
