在PHP上接受使用CURL的cookie

Question

I'm trying to run a log in script over my Centos machine. What the script does is logging in with a username and password to a 3rd party site and gets the page contents.

Although the script works perfectly in my PC (XAMPP at Windows), in my Centos box it seems not work. After logging in, it keeps redirecting to the log in page (although the log in succeed). Here is the code:

function request($url,$post)
{
$ch = curl_init();
$curlConfig = array(
    CURLOPT_URL            => $url,
    CURLOPT_POST           => 1,
    CURLOPT_RETURNTRANSFER => 1,
    CURLOPT_COOKIEFILE => 'cookies.txt',
    CURLOPT_COOKIEJAR => 'cookies.txt',
    CURLOPT_USERAGENT => '"Mozilla/5.0 (Windows; U; Windows NT 5.1; en-US; rv:1.8.1.6) Gecko/20070725 Firefox/2.0.0.6"',
    CURLOPT_FOLLOWLOCATION => 1,
    CURLOPT_REFERER => $url,
    CURLOPT_POSTFIELDS     => $post
);
curl_setopt_array($ch, $curlConfig);
$result = curl_exec($ch);
curl_close($ch);
return $result;
}
echo request('site.com/login.php',array("username" => "test", "password" => "test", "submit" => ""));

How would this code could be transfered to a working code in a Linux machine? What part am I missing? Thank you very much,

Regards.

Code was indeed perfect. All was needed is to create the file and give it the proper permissions. Inspired by Marc B. Thank you.
