Question

我正在尝试将header.php放在我的引导代码之上，如下所示。但是，我的代码似乎不起作用。好像header.php中的内容根本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。

- 我必须更换所有＆＃34;到＆＃39;？

使用以下方式调用它：

<?php

include 'header.php';

?>

此内容：

<?php
    session_start();

?>

This is what happens when i run just the header.php

Answer 1

看起来你没有正确导入bootstrap。头文件中的类没有得到bootstrap.css。重新检查bootstrap目录。在浏览器中打开“开发者工具”，然后按网络选项卡按f5，看看bootstrap.css

Answer 2

将索引设置为php文件而不是.html并正常工作

在bootstrap html代码中使用php
