我的程序代碼
原生導出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");
$conn = mysqli_connect("localhost","zhouqi","445864742") or die("無法連接數據庫");
mysqli_select_db($conn,"test");
mysqli_set_charset($conn,'utf8');
$sql = "SELECT * FROM student";
$result = mysqli_query($conn,$sql);
echo "ID號\t姓名\t分數\t\n";
while ($row = mysqli_fetch_array($result)){
echo $row[0]."\t".$row[1]."\t".$row[2]."\t\n";
}
?>
\t為換格 \n為換行
PHPEXCEL用法

mysqli_select_db($conn,Conf::$db_dbname);//選擇數據庫
