我有两个页面 home.php 和 header.php 现在头文件有顶部导航栏，将包含在 home.php 页面中。我在 header.php 中使用了引导下拉菜单，它正在工作很好，但是当我在 home.php 中包含 header.php 时，导航栏看起来很完美，但是下拉菜单不起作用，所以请帮忙。这是我的代码
标题.php
<?php
if(!isset($_SESSION))
{
session_start();
}
if(isset($_SESSION['user']))
{
$user=$_SESSION['user'];
}
?>

发生这种情况是因为您的标记无效，因为您两次嵌入了 html 标记。
