我的程序代码

原生导出Excel文件

<?php
header(\'Content-type: text/html; charset=utf-8\');
header("Content-type:application/vnd.ms-excel");
header("Content-Disposition:filename=test.xls");

$conn = mysqli_connect("localhost","zhouqi","445864742") or die("无法连接数据库");
mysqli_select_db($conn,"test");
mysqli_set_charset($conn,\'utf8\');
$sql = "SELECT * FROM student";
$result = mysqli_query($conn,$sql);
echo "ID号\\t姓名\\t分数\\t\\n";
while ($row = mysqli_fetch_array($result)){
    echo $row[0]."\\t".$row[1]."\\t".$row[2]."\\t\\n";
}
?>

 

\\t为换格   \\n为换行

 

 

phpEXCEL用法

 

 

 

<?php
require_once(phpexcel_dir()); //引入PHPExcel 类

$objPHPExcel=new PHPExcel();
//获得数据  ---一般是从数据库中获得数据

$conn = mysqli_connect(Conf::$db_host,Conf::$db_username,Conf::$db_password) or die("无法连接数据库");//连接数据库主机，用户名，密码 配置文件里设置
mysqli_select_db($conn,Conf::$db_dbname);//选择数据库
mysqli_set_charset($conn,\'utf8\'); //设置字符集

 

 

 

//左连接连接三张表
$sql = "SELECT
              a.id,a.order_sn,a.status,a.rev_name,a.rev_addr,a.rev_mail,a.rev_post,a.rev_mobile,b.account_name,c.brands_name,a.project
            FROM ec_orders AS a
            LEFT JOIN ec_account AS b ON a.account_id = b.id

            LEFT JOIN ec_goods_brands AS c ON a.brands_id = c.id
            WHERE a.is_del = 0 AND b.is_del = 0 AND c.is_del =0";
$result = mysqli_query($conn,$sql);
$data = array();
$i = 0;
while ($row = mysqli_fetch_array($result)){
    $data[$i][\'id\'] = $row[\'id\'];
    $data[$i][\'order_sn\'] = $row[\'order_sn\'];
    //订单的状态   0:待确认 1:已确认/待付款 2:已付款/待发货 3:发货中 4:已发货 5:买家收货确认 6:订单完成 7:买家取消订单 8:卖家取消订单
