	    $outputBuffer = fopen("php://output", 'w');
	    foreach($data as $val) {
		    foreach ($val as $key => $val2) {
		     $val[$key] = iconv('utf-8', 'gbk', $val2);
				// CSV的Excel支持GBK编码，一定要转换，否则乱码,转成gbk以兼容office乱码的问题
		    }
	      fputcsv($outputBuffer, $val);
	    }
	    fclose($outputBuffer);
