Question

I’m using this code to import images from a rss news feed.

$source_xml = simplexml_load_file("http://feeds.bbci.co.uk/news/uk/rss.xml");
foreach ($source_xml->channel->item as $rss) {
    $namespace      = "http://search.yahoo.com/mrss/";
    $images         = $rss->children($namespace)->thumbnail[1]->attributes();
    $image          = $images['url'];
    echo $image; echo "<br />";
}

The code seems to be working, however at some point in the loop, it just stops! The loop never goes through the whole rss feed. I tried to find out why it stops, but I just don’t seem to get anywhere. Any ideas?

I got error:

Fatal error: Call to a member function attributes() on a non-object in ...

$rss->children($namespace)->thumbnail[1]->attributes() is empty for some line and you got fatal error.

Try this:

$source_xml = simplexml_load_file("http://feeds.bbci.co.uk/news/uk/rss.xml");
foreach ($source_xml->channel->item as $rss) {
    $namespace      = "http://search.yahoo.com/mrss/";
    if(!is_object($rss->children($namespace)->thumbnail[1]))continue;
    $images         = $rss->children($namespace)->thumbnail[1]->attributes();
    $image          = $images['url'];
    echo $image; echo "<br />";
}
