foreach ($xml->channel->item as $item)

    echo $article['pubDate'] = $item->pubDate; 
    echo $article['description'] = (string) trim($item->description); 

} 

Answer 1

如果urlencode()的URL參數（即$movie），它應該正常工作。

例子：

$data = file_get_contents('http://news.google.com.mx/news?hl=es&gl=mx&q='. urlencode($movie) .'&bav=on.2,or.r_gc.r_pw.r_cp.r_qf.,cf.osb&um=1&ie=UTF-8&output=rss') 

Answer 2

你需要用的$movie中進行urlencode。我還添加了一個內容類型標題，以便您可以指定在該提要中使用的UTF-8編碼，併爲非英文字符正確渲染文本。

<?php 

header('Content-Type:text/html;charset=utf-8'); 

$movie = 'harry potter'; 
$url = 
$data = file_get_contents('http://news.google.com.mx/news?hl=es&gl=mx&q='.urlencode($movie).'&bav=on.2,or.r_gc.r_pw.r_cp.r_qf.,cf.osb&um=1&ie=UTF-8&output=rss'); 

$xml = new SimpleXMLElement($data); 
$channel = array(); 
$channel['title'] = $xml->channel->title; 

foreach ($xml->channel->item as $item) 
{ 
    //echo $article['title'] = $item->title; 
    //echo $article['link'] = $item->link; 
    echo $article['pubDate'] = $item->pubDate; 
    echo $article['description'] = (string) trim($item->description); 
} 

?>
