从 RSS 提要获取附件 img url [英] Get enclosure img url from rss feed

问题描述

我在 php 中的 rss 提要有问题.我想从enclosure"中获取 img-url，但它不起作用.

I have a problem with an rss feed in php. I want do get the img-url from "enclosure" but it´s not working.

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，有时没有附件标签，因此即使缺少它也必须工作.

Important to note is that sometimes there is not enclosure-tag with so it must work even if it is missing.

谢谢！此致查尔斯
