Question

this is myvery simple code:

adam@cka: php test.php
NULL

is my XML broken? or there's a better function in php to read xml file?

i can see the elment exists in the XML file and i downloaded the file correctly in my computer.

Answer 1

SimpleXML returns an object, not an array. Try this:

<?php
 $xml = simplexml_load_file('http://news.yahoo.com/rss/us');
 var_dump($xml->channel);
?>

Answer 2

Something like this:

$rss = simplexml_load_file('http://news.yahoo.com/rss/us');

echo $rss->channel->title;

foreach ($rss->channel->item as $item) {
   echo $item->link. " -- " .$item->title;
   echo $item->pubDate;
   echo $item->description;
}
