Get FeedBurner Subscriber Count with cURL

$ch = curl_init();
curl_setopt($ch,CURLOPT_URL,'https://feedburner.google.com/api/awareness/1.0/GetFeedData?id=7qkrmib4r9rscbplq5qgadiiq4');
curl_setopt($ch,CURLOPT_RETURNTRANSFER,1);
curl_setopt($ch,CURLOPT_CONNECTTIMEOUT,2);
$content = curl_exec($ch);
$subscribers = get_match('/circulation="(.*)"/isU',$content);
curl_close($ch);

The $subscribers variable will then be your subscriber count, for echoing out (or whatever). You'll need to replace the ID at the end of the second line with your feed's ID (find it). You'll also need to have the Awareness feature of FeedBurner enabled.

    I used the above code with my id:

    but i get an error message like this:

    Fatal error: Call to undefined function get_match() in /home/boom/public_html/subscribers.php on line 14

    my id is valid, checked the xml file: https://feedburner.google.com/api/awareness/1.0/GetFeedData?id=c0plc3tf94g80eaqavodrdsgvg

    Is it a webhosting issue maybe? My server supports PHP Version 5.2.6

    Thanx!

      I think that function probably needs to be defined elsewhere…

      function get_match($regex,$content)
      {
        preg_match($regex,$content,$matches);
        return $matches[1];
      }

    curl_setopt($ch,CURLOPT_CONNECTTIMEOUT,2);
    $content = curl_exec($ch);
    $subscribers = get_match(‘/circulation=”(*)”/isU’,$content);
    curl_close($ch);

    Nice information! It can be used with images and CSS to produce great result…

    The avarnes API is no longer available. We need to find a way to get the amount of subscribers without the API.

Posting Code

We highly encourage you to post problematic HTML/CSS/JavaScript over on CodePen and include the link in your post. It's much easier to see, understand, and help with when you do that.

Markdown is supported, so you can write inline code like `<div>this</div>` or multiline blocks of code in in triple backtick fences like this:

```
<script>
  function example() {
    element.innerHTML = "<div>code</div>";
  }
</script>
```
