php简单操作excel

$objPHPExcel = new \PHPExcel();
$objPHPExcel->setActiveSheetIndex(0)
    //Excel的第A列，uid是你查出数组的键值，下面以此类推
    ->setCellValue('A1','订单')
    ->setCellValue('B1', '预约人')
    ->setCellValue('C1', '密码')
    ->setCellValue('D1', '地址');
/*以下就是对处理Excel里的数据， 横着取数据，主要是这一步，其他基本都不要改*/
$num=1;
foreach($data as $k=>$v) {
    $num+= 1;
    $objPHPExcel->setActiveSheetIndex(0)
        //Excel的第A列，uid是你查出数组的键值，下面以此类推
        ->setCellValue('A'.$num, $v['id'])
        ->setCellValue('B'.$num, $v['username'])
        ->setCellValue('C'.$num, $v['password'])
        ->setCellValue('D'.$num, $v['address']);
}
$objPHPExcel->getActiveSheet()->setTitle('User');
$objPHPExcel->setActiveSheetIndex(0);
