What's wrong here?

[syntax=php]<?php
function php_net_feed($limit){
$output = array();
$feed_url = 'http://php.net/feed.atom';
$feed = simplexml_load_file($feed_url);
$x = 1;

foreach ($feed->entry as $item) {
if ($x <= $limit){
$title = $item->title;
$url = $item->id;

$output[] = array(
'title' = $title,
'url' = $url
);
}
$x++;
}

return $output;
}

$feed = php_net_feed(5);

?>
<ul>

<?php
foreach ($feed as $item) {
echo '<li>', $item['title'], '</li>';
}
?>

</ul>[/syntax]

This is the example

[syntax=text]<entry xmlns="http://www.w3.org/2005/Atom" xml:base="entries/2012-11-22-1.xml">

I usually work these things out by looking at the result of the parsing, it's not always obvious from the XML directly.

Try adding
[syntax=php]print_r($item);[/syntax]
inside your loop, and maybe set $x to 1 for testing, and see what you get :)

If that array is in the variable $data then you want $data['p'][0]
