你要这个：
curl_setopt($ch, CURLOPT_USERPWD, $username . ":" . $password);
Zend有一个REST客户端和zend_http_client，我敢肯定PEAR有某种包装。但是它很容易自己完成。
因此，整个请求可能如下所示：
$ch = curl_init($host);curl_setopt($ch, CURLOPT_HTTPHEADER, array('Content-Type: application/xml', $additionalHeaders));curl_setopt($ch, CURLOPT_HEADER, 1);curl_setopt($ch, CURLOPT_USERPWD, $username . ":" . $password);curl_setopt($ch, CURLOPT_TIMEOUT, 30);curl_setopt($ch, CURLOPT_POST, 1);curl_setopt($ch, CURLOPT_POSTFIELDS, $payloadName);curl_setopt($ch, CURLOPT_RETURNTRANSFER, TRUE);$return = curl_exec($ch);curl_close($ch);
