PHP fsockopen() cookies

>我正在尝试创建一个"远程登录"站点，但是当我尝试以下代码时，我收到有关cookie被禁用的错误，我已经在谷歌上搜索了解决方案，但是唯一解决的情况是cURL方式（cookie jar），我该如何解决cookie问题？我怎样才能找到网站需要的cookie（它有大约10个）？

<?php
$vars = array(
    'email' => "*****",
    'pass'=>"*****"
    );
$content = http_build_query($vars);
$host = 'www.site.com';
$service_uri = '/login.php';
$vars ='login_mode=1';
$header = "Host: $host'r'n";
$header .= "User-Agent: PHP Script'r'n";
$header .= "Content-Type: application/x-www-form-urlencoded'r'n";
$header .= "Referer: http://www.site.com 'r'n";
$header .= "Content-Length: ".strlen($content)."'r'n";
$header .= "Connection: close'r'n'r'n";
$fp = fsockopen("".$host,80, $errno, $errstr);
if (!$fp)
{
    echo "$errstr ($errno)<br/>'n";
    echo $fp;
}
else
{
    fputs($fp, "POST $service_uri  HTTP/1.1'r'n");
    fputs($fp, $header.$content);
    while(!feof($fp))
    {
        echo fgets($fp, 128);
    }
    fclose($fp);
}
?>
