simplexml_load_file doesn't reload file

[DjMikeS]

Hi all,

 

I've got this script to read an rss feed and display it on my website. I only want it to display the first 10 records, and leave out any items that don't belong to the "nieuws" (in english: news) category.

 

So far so good though I think it can be done a little nicer...

The real problem is that it doesn't seem to reload the feed when I reload my website...I still see the old news items while the feed has been updated...

 

Do you know how to solve this?

 

My code:

<?php
try {
	$strFeed = "http://feeds.feedburner.com/tweakers/mixed";
	if (!$sxml = simplexml_load_file($strFeed)) {
		$strError = "RSS feed not available at this moment";
		Throw New Exception();
	}

	$i = 0;
	foreach ($sxml->channel->item as $item){
		if (stristr($item->category, 'Nieuws') AND $i < 10) {
			echo "<li><b><a href=\"$item->link\">$item->title</a></b></li>\n";
		$i++;
		}
	}
	unset ($sxml);
}

catch (Exception $e) {
	echo $strError;
}
?>

Do you know if some sort "expires" header involved? Feedburner may even be limiting your IP's refreshes, who knows. Nothing relevant here: http://us.php.net/manual/en/function.simplexml-load-file.php , but you may want to browse that part of the Manual.

Thnx tmallen, I know feedburner isn't limiting my ip, because when I open the feed in my browser I can refresh as much as I like...

 

I think php is caching the feed or something...

The other solution would be to create a cronjob that automagically downloads the correct file every hour or so...but I would like to have it in sync....

 

edit:

I read something about the headers so I added this to my site:

 

header('Expires: Fri, 25 Dec 1980 00:00:00 GMT'); // time in the past

header('Last-Modified: ' . gmdate( 'D, d M Y H:i:s') . 'GMT');

header('Cache-Control: no-cache, must-revalidate');

header('Pragma: no-cache');

header('Content-Type: text/html');

 

But no luck yet....
