在这里，应该这样做：
curl_setopt($this->_ch, CURLOPT_URL, $this->_url);curl_setopt($this->_ch, CURLOPT_HEADER, 1);curl_setopt($this->_ch, CURLOPT_RETURNTRANSFER, 1);$response = curl_exec($this->_ch);$info = curl_getinfo($this->_ch);$headers = get_headers_from_curl_response($response);function get_headers_from_curl_response($response){ $headers = array(); $header_text = substr($response, 0, strpos($response, "rnrn")); foreach (explode("rn", $header_text) as $i => $line) if ($i === 0) $headers['http_pre'] = $line; else { list ($key, $value) = explode(': ', $line); $headers[$key] = $value; } return $headers;}
