PHP e XML — Google Weather API problem with language selection
I want show weather information from xml to this URL: http://www.google.com/ig/api?weather=roma&hl=it using this script:
<?
$xml = simplexml_load_file('http://www.google.com/ig/api?weather=roma&hl=it');
$information = $xml->xpath("/xml_api_reply/weather/forecast_information");
$current = $xml->xpath("/xml_api_reply/weather/current_conditions");
$forecast_list = $xml->xpath("/xml_api_reply/weather/forecast_conditions");
?>
<html>
<head>
<title>Google Weather API</title>
</head>
<body>
<h1><?= print $information[0]->city['data']; ?></h1>
<h2>Today's weather</h2>
<div class="weather">
<img src="<?= 'http://www.google.com' . $current[0]->icon['data']?>" alt="weather"?>
<span class="condition">
<?= $current[0]->temp_f['data'] ?>° F,
<?= $current[0]-&g开发者_开发百科t;condition['data'] ?>
</span>
</div>
<h2>Forecast</h2>
<? foreach ($forecast_list as $forecast) : ?>
<div class="weather">
<img src="<?= 'http://www.google.com' . $forecast->icon['data']?>" alt="weather"?>
<div><?= $forecast->day_of_week['data']; ?></div>
<span class="condition">
<?= $forecast->low['data'] ?>° F - <?= $forecast->high['data'] ?>° F,
<?= $forecast->condition['data'] ?>
</span>
</div>
<? endforeach ?>
</body>
</html>
But the script does not show any output, if I delete the language specification (&hl=it) from simplexml_load_file's parameters, it works.
Error_log_php Output:

user this code because external xml dont read from your site so use this curl code
<?php
/*$xml = simplexml_load_file('http://www.google.com/ig/api?weather=islamabad');
$information = $xml->xpath("/xml_api_reply/weather/forecast_information");
$current = $xml->xpath("/xml_api_reply/weather/current_conditions");
$forecast_list = $xml->xpath("/xml_api_reply/weather/forecast_conditions");*/
$placename = 'islamabad'; // city where you want local weather
$place=urlencode($placename);
$place = utf8_encode($place);
$url = 'http://www.google.com/ig/api?weather='.$place;
$ch = curl_init();
curl_setopt ($ch, CURLOPT_RETURNTRANSFER, 1);
curl_setopt ($ch, CURLOPT_URL, $url);
curl_setopt ($ch, CURLOPT_USERAGENT, $_SERVER['HTTP_USER_AGENT']);
curl_setopt ($ch, CURLOPT_TIMEOUT, 60);
curl_setopt ($ch, CURLOPT_FOLLOWLOCATION, 0);
$raw_data = curl_exec ($ch);
curl_close ($ch);
$xml = simplexml_load_string($raw_data);
echo $condition = $xml->weather->current_conditions->condition['data'];
echo $temp_f = $xml->weather->current_conditions->temp_f['data'];
echo $humidity = $xml->weather->current_conditions->humidity['data'];
echo $icon = $xml->weather->current_conditions->icon['data'];
echo $wind_condition = $xml->weather->current_conditions->wind_condition['data'];
?>
I solved the problem adding these lines:
$url = file_get_contents('http://www.google.com/ig/api?weather=roma&hl=it');
$xml = iconv("iso-8859-1", "utf-8", $url);
$xml = simplexml_load_string($xml);
加载中,请稍侯......
