在引导程序的html代码中使用php

我想在我的引导程序代码上面放置使用header.php，如下所示。但是，我的代码似乎不工作。就好像header.php中的内容没有添加到代码的顶部。我正在使用在本地主机上运行的phpmysql服务器来运行php文件。在引导程序的html代码中使用php

尚北道我已经全部更换为“以“

使用调用它：

<?php 

include 'header.php'; 

?>

此内容：

<?php 
    session_start(); 

?>

写'需要“的header.php” ;'在你的主文件中，有什么问题？ – JapanGuy

@JapanGuy更新：我打电话使用<？php include'header.php'; ？> –

如果您访问地址栏中的header.php，会发生什么情况？ – JapanGuy
