Question

Can anybody tell me why this CURL code only works on my local server and not on live server?
Tried on 3 different hosting and nothing works.

Checked everything on live
1) Curl enabled
2) PHP version is OK
3) Curl executes without any error but no result

Its been 3 days and I am not able to find any solution
please help.

error_reporting(1);
set_time_limit(1500);

$fname=time().'_myfile.flv';
header('Content-type: video/x-flv');
header("Content-Type: application/octet-stream");
header("Content-Disposition: attachment; filename=\"$fname\"");

    $ch = curl_init() or die("Error");
    curl_setopt($ch, CURLOPT_USERAGENT, USERAGENT);
    curl_setopt($ch, CURLOPT_URL, $url);    
    curl_setopt($ch, CURLOPT_RETURNTRANSFER, 0);  
    if(curl_exec($ch) === FALSE) 
    {
        die("Curl failed: " . curl_error($ch));  // Never goes here
    }

    curl_close($ch);

?>

Do a curl_getinfo($ch) after exec to see the response code returned by the server.
