Question

我在php中使用rss feed时遇到问题。我想从“封闭”获取img-url但它不起作用。

我刚才的代码：

$rss = simplexml_load_file($url);

$i = 0;
if($rss)
{
$items = $rss->channel->item;
foreach($items as $item)
{
$title = $item->title;
$link = $item->link;
$published_on = $item->pubDate;
$phpDate = strtotime($published_on);
$enclosure = $item['enclosure'][0]['url'];

来自RSS：

<enclosure url="http://www.svenskafans.com/image/7/141433/Snalla-Pelle-stanna-i-Gefle.jpg" lenght="51265" type="image/jpeg" />

需要注意的是，有时候没有enclosure-tag，所以即使它丢失也必须有效。

谢谢！最好的祝福查尔斯

怎么样：

$rss=simplexml_load_file('http://www.svenskafans.com/rss/team/77.aspx');
foreach ($rss->channel->item as $item) {
    if (isset($item->enclosure)) {
        echo $item->enclosure['url'].'<br>';
    }
}

输出：
