curl get获取到一个utf-8 json字符串，用json_decode解析说格式不对。

    $ch = curl_init();//初始化curl    curl_setopt($ch,CURLOPT_URL,$url);    curl_setopt($ch,CURLOPT_RETURNTRANSFER,1);    curl_setopt($ch, CURLOPT_HEADER, 0);            $data=curl_exec($ch);    print_r(json_decode($data));    echo json_last_error_msg();//提示符号错误

用浏览器输入$url，确实反馈回来一个json数据。怎么弄？bom去头又怎么弄。好像去不掉。

.....
$data=curl_exec($ch);
echo base64_encode($data);

加上
curl_setopt($ch, CURLOPT_FOLLOWLOCATION, true);
