导出的使用：

    //导出
    public function create_xls() {
        $industry_list = M('welfare')->field('welfare_name')->select();
        $data = array();
        array_push($data, array('福利名称'));
        foreach ($industry_list as $key => $value) {
            array_push($data, array($value['welfare_name']));
        }
        create_xls($data, '福利');
    }

导入：

    //导入
    public function upload_xls() {
        $upload = new ThinkUpload();
        $upload->maxSize = 3145728;

        $data = import_excel($upload->rootPath . $result['savepath'] . $result['savename']);
        delDirAndFile($upload->rootPath . $result['savepath']);

        $list = array();
        unset($data[1]);
        $i = 0;

        foreach ($data as $k => $v) {

            $info = M('welfare')->where($param)->find();
            if ($info)
                continue;

            $list[$i]['welfare_name'] = $v[0];
            $i++;
        }

        if ($i) {
            M('welfare')->addAll($list);
