CURL (PHP)中的Cookie问题- CURL头文件中没有附加Cookie信息

我有这样的代码

<?php
    $mLoginUrl = "https://www.test.com/login";
    $mCookieFile = dirname(__FILE__).'/tmpCookies/cookie'.rand().'.txt';
    define('USER_AGENT', 'Mozilla/5.0 (Windows NT 5.1) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/35.0.2309.372 Safari/537.36');
    define('COOKIE_FILE', $mCookieFile);
    define('LOGIN_FORM_URL', $mLoginUrl);
    define('LOGIN_ACTION_URL', $mLoginUrl);
    $postValues = array(
        'user[email]' => "mymail@email.com",
        'user[password]' => "mypassword"
    );
    $headers = Array(
                "Accept: text/xml,application/xml,application/xhtml+xml,text/html;q=0.9,text/plain;q=0.8,image/png,*/*;q=0.5",
                "Cache-Control: max-age=0",
                "Connection: keep-alive",
                "Keep-Alive: 300",
                "Accept-Charset: ISO-8859-1,utf-8;q=0.7,*;q=0.7",
                "Accept-Language: en-us,en;q=0.5",
                "Pragma: "
            );
    $curl = curl_init();
    curl_setopt($curl, CURLOPT_VERBOSE, TRUE);
    curl_setopt($curl, CURLOPT_URL, LOGIN_ACTION_URL);
    curl_setopt($curl, CURLOPT_POST, TRUE);
    curl_setopt($curl, CURLOPT_POSTFIELDS, http_build_query($postValues));
    curl_setopt($curl, CURLOPT_SSL_VERIFYPEER,FALSE);
    curl_setopt($curl, CURLOPT_SSL_VERIFYHOST, FALSE);
    curl_setopt($curl, CURLOPT_COOKIEJAR, COOKIE_FILE);
    curl_setopt($curl, CURLOPT_COOKIEFILE, COOKIE_FILE);
    curl_setopt($curl, CURLOPT_USERAGENT, USER_AGENT);
    curl_setopt($curl, CURLOPT_RETURNTRANSFER, TRUE);
    curl_setopt($curl, CURLOPT_REFERER, LOGIN_FORM_URL);
    curl_setopt($curl, CURLOPT_FOLLOWLOCATION, TRUE);
    curl_setopt($curl, CURLOPT_HTTPHEADER,$headers) ;
    curl_setopt($curl, CURLINFO_HEADER_OUT, TRUE);
    $res = curl_exec($curl);
    $info = curl_getinfo($curl);
    print_r($info['request_header']);
    exit;
?> 

这在我的本地计算机和我的一个服务器上运行良好，并显示以下输出

GET / HTTP/1.1

这意味着cookie是在CURL的头文件中创建和附加的(正如我们在CURL的头文件打印中看到的那样)。cookie文件也在上述位置创建。

但是在我的一个服务器上，代码没有按预期工作，并给出以下输出

POST /users/sign_in? HTTP/1.1 User-Agent: Mozilla/5.0 (Windows NT 5.1) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/35.0.2309.372 Safari/537.36 Host: www.test.com Referer: https://www.test.com/login Accept: text/xml,application/xml,application/xhtml+xml,text/html;q=0.9,text/plain;q=0.8,image/png,*/*;q=0.5 Cache-Control: max-age=0 Connection: keep-alive Keep-Alive: 300 Accept-Charset: ISO-8859-1,utf-8;q=0.7,*;q=0.7 Accept-Language: en-us,en;q=0.5 Content-Length: 76 Content-Type: application/x-www-form-urlencoded 

表示cookie信息不附加在CURL的标头中。我已经检查了cookie文件是在这个(有问题的)服务器上创建的，并且有cookie内容，但仍然cookie内容不包括在CURL头中。提到的临时cookie目录对所有用户都具有完全的权限。

问题服务器的PHP版本是5.4.19,CURL版本是7.19.7

有谁能帮忙吗?我已经尝试了所有在网上找到的解决方案。
