        $PHPExcel=$PHPReader->load($filename);
        $currentSheet=$PHPExcel->getSheet(0);
        $allColumn=$currentSheet->getHighestColumn();
        $allRow=$currentSheet->getHighestRow();
        for($currentRow=2;$currentRow<=$allRow;$currentRow++){
            $arr['id'] = $PHPExcel->getActiveSheet()->getCell('A'.$currentRow)->getValue();
            $arr['catId'] = $PHPExcel->getActiveSheet()->getCell('B'.$currentRow)->getValue();
            $arr['parentId'] = trim($PHPExcel->getActiveSheet()->getCell('C'.$currentRow)->getValue());
            $arr['name'] = $PHPExcel->getActiveSheet()->getCell('D'.$currentRow)->getValue();
            $arr['catClass'] = $PHPExcel->getActiveSheet()->getCell('E'.$currentRow)->getValue();
            $arr['state'] = $PHPExcel->getActiveSheet()->getCell('F'.$currentRow)->getValue();
            $arr['one'] = $PHPExcel->getActiveSheet()->getCell('G'.$currentRow)->getValue();
            $data[] =$arr;
        }
        return $data ;
    }

    function exportexcel($data=array(),$title=array(),$filename='report'){
        header("Content-type:application/octet-stream");
        header("Accept-Ranges:bytes");
        header("Content-type:application/vnd.ms-excel");
        header("Content-Disposition:attachment;filename=".$filename.".xls");
        header("Pragma: no-cache");
        header("Expires: 0");

        if (!empty($title)){
            foreach ($title as $k => $v) {
                $title[$k]=iconv("UTF-8", "GBK",$v);
            }
            $title= implode("\t", $title);
            echo "$title\n";
        }
        if (!empty($data)){
            foreach($data as $key=>$val){
                foreach ($val as $ck => $cv) {
                    $data[$key][$ck]=iconv("UTF-8", "GBK", $cv);
                }
            $data[$key]=implode("\t", $data[$key]);
            }
