        ob_start();

        header("Content-Type: text/csv");

        header("Content-Disposition:filename=".$filename);

        $fp=fopen('php://output','w');

        fwrite($fp, chr(0xEF).chr(0xBB).chr(0xBF));//转码 防止乱码(比如微信昵称(乱七八糟的))

        fputcsv($fp,$tileArray);

        $index = 0;

        foreach ($dataArray as $item) {

            if($index==1000){

                $index=0;

                ob_flush();

                flush();

            $index++;

            fputcsv($fp,$item);
