Limiting number of headlines isn't working

magpie instructions don't seem to work.

I added RSS feed using your simple guide. So far so good. Only one small hitch. I am getting about 35 headlines and I want to limit it to more like 20. I checked magpie and got this instruction.

You want to display the 10 (or 3) most recent headlines, but the RSS feed
contains 15.


$num_items = 10;
$rss = fetch_rss($url);

$items = array_slice($rss->items, 0, $num_items);


Rather then trying to limit the number of items Magpie parses, a much simpler,
and more flexible approach is to take a "slice" of the array of items. And
array_slice() is smart enough to do the right thing if the feed has less items
then $num_items.

See: [php.net...]

I located the $rss = fetch_rss($url); in the feed.php code and replaced it with the above code since it is duplicated and expanded in the replacement code.

I uploaded feed.php to my site and nothing changed. Even when i open mydomain/rssdemo/feed.php there are still all the headlines. (yes, i ctl/refreshed to make sure)

So, where did I go wrong. I noticed this same question was asked when the simple guide was first posted but no one responded.

My guess is you still have it as the following:

foreach($rss-items as $item) { etc...

You should be echoing the results as follows now with your new code:

foreach($items as $item) {
echo '<pre>'; print_r($item); echo '</pre>';

try that and see what that gets you.

Actually, if you check the guide, the code foreach($rss-items as $item) does not appear and it doesn't appear in my code either as all I did was change the RSS feed URL.
[webmasterworld.com ]

I will gladly add it if you tell me where in feed.php I should insert it. Thanks for the interest.

PS.... I copy/pasted that snippet below the code in my original post and it really screwed things up (added a bunch of the headlines in plain text above my existing list and spread my page out something awful) so obviously, I need to put it someplace else.

Sorry, I didn't actually look at the guide. I was giving you code so that you can see if the number of results was accurate (10). From the guide, it looks like you have to change the following code:
