例如，如何在不手动更改所有页面的情况下，编辑一个HTML文件的标题并使它对所有其他页面都相同？

Question

More in-depth; for example, about any website at the moment has a navigation bar. With hundreds of pages, as an example, how would you edit it accordingly on one page - which will modify the navigation bar on all other pages you've got without changing each page its navbar manually?

Answer 1

All you need to do is to create a common have header file and include in every page.

This can be done with PHP s include or require .

Answer 2

well, it depends: because this task is normally performed by the server , each server platform manage this problem in a different way. for instance : ASP.NET applications using a MasterPage mechanism in order to define a main template for the entire site, with "frames" that changes from page to page.

on the client side this is normally performed by iframe tags... so it really depends which platform are you using and if your stratedgey focus on the server side or on the client side

Answer 3

Well a shortcut, you could do this.

Index.php

   ///header code
              <? 
if(empty($pg))
$var = "p/home.php";

if(empty($_SERVER["QUERY_STRING"])) {
include($var);
} else {
include("p/$pg.php");
}
?>
    ////footer code

Now just link you links to "?pg=NAME_OF_THE_PAGE" without the ".php" and you will have a standard index that you can chage menu, header and footer that will change for all pages.

Note: the pages that you will create, just put the content, with no header or footer.

Hope it helps.

Answer 4

As programming student said, use include or require :

header.php

<div class="header">
   <p>this is a header</p>
</div>

index.php

<?php require_once 'header.php'; ?>
