Question

目前我正在开发一个允许用户进行交易，销售和购买的网站。我使用PHP和Bootstrap作为CSS，我创建了导航。我也创建了注册页面，但是当他们登录到他们的个人资料时，我希望他们的标题能够改变。

我知道这可能是一个愚蠢的问题，但是一旦用户登录后如何更改标题以替换链接？我想我必须查询JavaScript？

的index.php

<?php 

       $pageTitle = "Vomica";
       $section = "home";

?>

<?php include 'INC/header.php' ?>


       <div class="container-fluid">



       </div>

<?php include 'INC/footer.php' ?>

的header.php

<html lang="EN">

    <head>

        <title> <?php echo $pageTitle; ?> </title>
