refer to the documentation :请参阅文档：

header() must be called before any actual output is sent, either by normal HTML tags, blank lines in a file, or from PHP. header() 必须在发送任何实际的 output 之前调用，无论是通过普通的 HTML 标记、文件中的空行还是来自 PHP。 It is a very common error to read code with include, or require, functions, or another file access function, and have spaces or empty lines that are output before header() is called.在调用 header() 之前，使用 include 或 require 函数或其他文件访问 function 读取代码是非常常见的错误，并且在 output 中有空格或空行。 The same problem exists when using a single PHP/HTML file.使用单个 PHP/HTML 文件时也存在同样的问题。

<?php
// header must be before any sent output 
header("Content-Type: application/vnd.msword");
header("Expires: 0");
header("Cache-Control: must-revalidate, post-check=0, pre-check=0");
header("content-disposition: attachment;filename=hasilekspor.doc");
 ?>
<html>
...
</html>
