thinkphp利用PHPExcel导出数据实践

下面是我利用PHPExcel导出数据到excel的一次实践。

第一步，当然是到PHPExcel官网去下载phpexcel插件，将其放到thinkphp的vendor目录下。

第二，将到入数据的具体逻辑封装到工具类中。具体逻辑代码如下：

class UntilLogic
{
    public function phpExcelList($field, $list, $title='文件')
    {
        vendor('phpExcel.PHPExcel');
        $objPHPExcel = new \PHPExcel();
        $objWriter = new \PHPExcel_Writer_Excel5($objPHPExcel); //设置保存版本格式
        foreach ($list as $key => $value) {
            foreach ($field as $k => $v) {
                if ($key == 0) {
                    $objPHPExcel->getActiveSheet()->setCellValue($k . '1', $v[1]);
                }
                $i = $key + 2; //表格是从2开始的
                $objPHPExcel->getActiveSheet()->setCellValue($k . $i, $value[$v[0]]);
            }

        }
        header("Pragma: public");
        header("Expires: 0");
        header("Cache-Control:must-revalidate, post-check=0, pre-check=0");
        header("Content-Type:application/force-download");
        header("Content-Type:application/vnd.ms-execl");
        header("Content-Type:application/octet-stream");
        header("Content-Type:application/download");;
        header('Content-Disposition:attachment;filename='.$title.'.xls');
        header("Content-Transfer-Encoding:binary");
//        $objWriter->save($title.'.xls');
        $objWriter->save('php://output');
    }
}

第三步，读取需要下载数据，和组合excel数据标题$field参数，直接调用第二步的方法。

opublic function outExcelRecharge() {
        $where = "1=1";
        $data = $dbEngin->field('transactions.*,u.name as uname, k.name as kname')->where($where)->order('id desc')->select();
        foreach ($data as $key => $value) {
            $data[$key]['price'] = number_format($data[$key]['price']/100,2);
            $data[$key]['uname'] = filterEmoji($value['uname']);
        }
        $field = array(
            'A' => array('id', 'ID'),
            'B' => array('user_id', '用户ID'),
            'C' => array('uname', '用户名称'),
            'D' => array('created', '时间'),
            'E' => array('order_id', '订单号'),
            'F' => array('price', '金额(元)'),
            'G' => array('coins', '充值金币数'),
            'H' => array('device_id', '设备ID'),
            'I' => array('ktv_id', 'ktvID'),
            'J' => array('kname', 'ktv名称'),
            'K' => array('status', '状态(paid:已付款,refunded:已退款,pending:处理中)')
        );
        $until = new UntilLogic();
        $until->phpExcelList($field, $data, '充值列表_' . date('Y-m-d'));
    }

以上就是比较常见也非常简单的phpexcle数据到出方式。
