Answer 1

Make sure that you have php-xml module installed and enabled in php.ini.

You can also change response format to json which is easier to handle. In that case you have to only add &format=json to url query string.

$rest_url = "http://api.facebook.com/restserver.php?method=links.getStats&format=json&urls=".urlencode($source_url);

And then use json_decode() to retrieve data in your script:

$result = json_decode($content, true);
$fb_like_count = $result['like_count'];
