PHP中的动态标题标签 [英] Dynamic Title Tag in PHP

问题描述

我正在尝试在网站上动态填充标题标签.我的 index.php 页面中有以下代码

I am trying to dynamically populate the title tag on a website. I have the following code in my index.php page

<?php $title = 'myTitle'; include("header.php"); ?>

以及我的标题页上的以下内容

And the following on my header page

<title><?php if (isset($title)) {echo $title;}
else {echo "My Website";} ?></title>

但是无论我做什么，我都无法让这段代码工作.有没有人有什么建议?

But no matter what I do, I cannot get this code to work. Does anyone have any suggestions?

谢谢

推荐答案

此方法有效(已测试 - 创建一个新文件夹，将第一行代码放在名为 index.php 的文件中，将第二行代码放在 header.php 中，运行它，检查标题栏).

This works (tested it - create a new folder, put your first line of code in a file called index.php and the second one in header.php, run it, check the title bar).

您应该仔细检查这两个文件是否在同一个文件夹中，并且您包含了正确的 header.php 来自 正确的 index.php.并确保 $title 没有在代码中的某处设置回 null.

You should double check if those two files are in the same folder, and that you're including the right header.php from the right index.php. And ensure that $title is not being set back to null somewhere in your code.

<title>TEST2<?php if ...
