Getting the number of feedburner subscribers?

I'm currently using this code to get the number of subscribers to my blog:

$whaturl="http://api.feedburner.com/awareness/1.0/GetFeedData?uri=http://feeds.feedburner.com/DesignDeluge"; 
$ch = curl_init();
curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);
curl_setopt($ch, CURLOPT_URL, $whaturl);
$data = curl_exec($ch);
curl_close($ch);
$xml = new SimpleXMLElement($data); 
$fb = $xml->feed->entry['circulation'];

but when I echo $fb it doesn't work (the whole file that $fb is being echoed on doesn't appear). Any ideas on why this isn't working?

Solution

  • If you take a look at $data before trying to load it with SimpleXMLElement, you'll see it contains the following portion of HTML code :

    <HTML><HEAD><meta http-equiv="content-type" content="text/html;charset=utf-8">
<TITLE>301 Moved</TITLE></HEAD><BODY>
<H1>301 Moved</H1>
The document has moved
<A HREF="http://feedburner.google.com/awareness/1.0/GetFeedData?uri=http://feeds.feedburner.com/DesignDeluge">here</A>.
</BODY></HTML>

    So, there's no way you'll find what you're looking for in there ;-)


    A solution could be to use the CURLOPT_FOLLOWLOCATION option (see curl_setopt), so curl follows redirections...

    ... But this doesn't seem to work either.


    Actually, when I try to load the URL that's given in the portion of HTML code I posted earlier :

    http://feedburner.google.com/awareness/1.0/GetFeedData?uri=http://feeds.feedburner.com/DesignDeluge

    I only get the following XML as return :

    <?xml version="1.0" encoding="utf-8" ?>
<rsp stat="fail">
    <err code="2" msg="This feed does not permit Awareness API access" />
</rsp>


    Are you sure you are using the right URLs / feeds ?
