cURL and Facebook problems - php

Question

I am using cURL to access a facebook page. Locally it works perfect, but when I upload it to my dev server, it breaks and returns an empty string. I've checked and cURL is installed on the server. Here's the code I use to access facebook:
$header = array();
$header[] = 'Accept: text/json';
$header[] = 'Cache-Control: max-age=0';
$header[] = 'Connection: keep-alive';
$header[] = 'Keep-Alive: 300';
$header[] = 'Accept-Charset: ISO-8859-1,utf-8;q=0.7,*;q=0.7';
$header[] = 'Accept-Language: en-us,en;q=0.5';
$header[] = 'Pragma: ';
$ch = curl_init();
curl_setopt($ch, CURLOPT_URL, 'http://facebook.com/feeds/page.php?format=json&id=135137236003');
curl_setopt($ch, CURLOPT_USERAGENT, 'Mozilla/5.0 (Windows; U; Windows NT 6.0; en-US; rv:1.9.0.11) Gecko/2009060215 Firefox/3.0.11 (.NET CLR 3.5.30729)');
curl_setopt($ch, CURLOPT_HTTPHEADER, $header);
curl_setopt($ch, CURLOPT_AUTOREFERER, true);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);
curl_setopt($ch, CURLOPT_FOLLOWLOCATION, 1);
curl_setopt($ch, CURLOPT_ENCODING, '');
curl_setopt($ch, CURLOPT_TIMEOUT, 20);
$result = curl_exec($ch);
curl_close ($ch);
Any help is appreciated!

Answer 1

Change the accept header to */* or application/json as facebook is sending the response header as application/json.
And change this url
http://facebook.com/feeds/page.php?format=json&id=135137236003
to
http://www.facebook.com/feeds/page.php?format=json&id=135137236003
as facebook is redirecting the non-www request to www requests. Though it works for you as put follow location, but it saves one reound trip
