PHP：获取过去一小时的提要内容
我只想获取外部RSS源的内容，并存储上一小时的条目 因此，我可以通过以下方式获取RSS提要：PHP：获取过去一小时的提要内容,php,rss,Php,Rss,我只想获取外部RSS源的内容，并存储上一小时的条目 因此，我可以通过以下方式获取RSS提要： $url = 'http://www.animenewsnetwork.com/all/rss.xml'; $feed = new DOMDocument(); $feed->load($url); $print_r($feed); // display content... 现在，$feed包含RSS提要的所有数据。我只想存储过去一小时内发布的条目的链接： $latest_posts = a
$url = 'http://www.animenewsnetwork.com/all/rss.xml';
$feed = new DOMDocument();
$feed->load($url);
$print_r($feed); // display content...
$feed$latest_posts = array(
$URL_1,
$URL_2,
$URL_3,
$URL_4,
//...
);
我该怎么做 您需要循环浏览提要并检查发布日期
//Loop through all the items
foreach ($feed->getElementsByTagName("item") as $item){
//get the pubDate of the time, and compare it to time (obviously for the 1 hour ago you could do time() - 3600, but for the interest of self-documenting code in this example I've used strtotime()
if (strtotime($item->getElementsByTagName("pubDate")->item(0)->nodeValue) >= strtotime("-1 hour")){
//If it is, add it to the array...
$latest_posts[] = $item->getElementsByTagName("link")->item(0)->nodeValue;
} else {
break; //If this post is more than 1 hour old, then so will the rest of them be, so break out of the loop.
}
}

将xml转换为数组的简单方法 您可以使用此代码对其进行转换
$feed = 'http://www.animenewsnetwork.com/all/rss.xml';
$feed_to_array = (array) simplexml_load_file($feed);
//OR $feed_to_array = (array) new SimpleXmlElement( file_get_contents($feed) );
// print_r($feed_to_array); // if you want see the array
$feeds_i_need = array();
foreach($feed_to_array['channel']['item'] as $item) {
if (strtotime($item['pubDate'] >= strtotime("-1 hour")))
$feeds_i_need[] = $item;
else
break; // I did break so it will stop loop for others
}
