求教php curl 取不到数据，什么原因？

我只能说你的curl手册没有看认真，CURLOPT_HTTPHEADER这个选项的用法肯定是按你自己想象的来的，实际上并不是这样，应该

curl_setopt($ch, CURLOPT_HTTPHEADER, array(
    'Accept: */*',
    'Accept-Charset: UTF-8,*;q=0.5',
    'Accept-Encoding: gzip,deflate,sdch',
    'Accept-Language: zh-CN,zh;q=0.8',
    'Connection: keep-alive',
    'Content-Type: application/x-www-form-urlencoded; charset=UTF-8',
    'Referer: http://fuzhou.8684.cn/',
    'User-Agent: Mozilla/5.0 (Windows NT 5.1) AppleWebKit/537.11 (KHTML, like Gecko) Chrome/23.0.1271.95 Safari/537.11',
    'X-Requested-With: XMLHttpRequest',
));
