php的Rss xml 示例 採集新浪新聞

simplexml_load_file  直接使用此函數：

header("Content-type:text/html;Charset=utf-8");
$content = simplexml_load_file('http://rss.sina.com.cn/news/allnews/sports.xml');
//print_r($content);
foreach ($content->channel->item as $key => $value) {
	echo $value->title.'<br/>'.$value->link.'<br/>';
}

如果是這種類型

<rss version="2.0">
	<channel>
		<title>
			<![CDATA[焦點新聞-新浪體育]]>
		</title>
.....

那麼title就是一個對象裏面的值 即 

foreach ($content->channel as $key => $value) {
	echo $value->title.'<br/>';
}

如果是

<xml_api_reply version="1">
<weather module_id="0" tab_id="0" mobile_row="0" mobile_zipped="1" row="0" section="0">
......

modeul_id, tab_id等就是數組裏的值 

foreach ($content['weather'] as $key => $value) {
	echo $value['module_id'].'<br/>';
}
