使用PHP curl获取cookie

Question

我正试图通过使用curl的超简单脚本发送cookie。以下是文件：

get_cookie.php：

...
$curl = curl_init("http://.../set_cookie.php");
$data = array('fname'=>"John", 'lname'=>"Brown");
curl_setopt($curl, CURLOPT_POSTFIELDS, http_build_query($data)); 
curl_setopt($curl, CURLOPT_HEADER, 0);
curl_setopt($curl, CURLOPT_RETURNTRANSFER, true);
curl_setopt($curl, CURLINFO_HEADER_OUT, true);
curl_setopt($curl, CURLOPT_FOLLOWLOCATION, true);
...
$response = curl_exec($curl);
...
// get cookies
preg_match_all('/^Set-Cookie:s*([^;]*)/mi', $response, $matches);
$cookies = array();
foreach($matches[1] as $item) {
parse_str($item, $cookie);
$cookies = array_merge($cookies, $cookie);
}
echo "cookies recived: <br>";
var_dump($cookies);

set_cookie.php：

...
if (isset($_POST["fname"])) {
setcookie("usr_name", "user_".$_POST["fname"], time()+60*60);
...
}

但在curl响应上，我没有得到任何cookie-$cookies数组为空(我已经检查过了-$_POST["fname"]已设置-POST数据已成功发送(。当我以标准方式调用set_cookie时，我从浏览器中获得所需的usr_namecookie。curl有什么问题？

您是否尝试过curl_getinfo($curl, CURLINFO_COOKIELIST)而不是手动解析响应以获取cookie？
