Php 如何将元标记的内容从正文回显到标题

我正在尝试一些不确定如何进行的事情

我有一个header.php文件

我把它包含在页面中，所以现在我想添加meta标记，但不想使用相同的描述和关键字

如果我使用一个div标签，我将该页面搜索引擎中的描述中的内容放在正文中，然后在头文件中回显它，这样做有效吗？使用什么编码

谢谢，希望您能理解header.php中的

：

    echo '<meta name="description" content = "'.$description.'">';
echo '<meta name="keywords" content = "'.$keywords.'">';

---

在

header.php

文件中，定义一个创建头的函数：

function header($description, $keywords) {
    ...
    echo "<meta name='description' content='$description' />";
    echo "<meta name='keywords' content='$keywords' />";
    ...
}

稍后，当它在页面中创建

DIV

时，它可以使用这些相同的变量

$pageTitle = 'Services';
$keyword = "Books a Party Hall and Room Rentals in Toronto";
$description = "Books a Party Hall and Room Rentals in Toronto. Halls rental for Events, Adult & Children's Birthday Parties, Photography, Wedding, Music and Fashion Show Shoots, Corporate Presentations, Baby Showers, Going Away and Engagement Parties."; 
include 'header.php';

在标题中输入此代码

<title><?php echo $pageTitle; ?></title>
<meta name="keywords" content="<?php echo $keyword; ?>">
<meta name="description" content="<?php echo $description; ?>">

感谢您回答我如何将此变量转换为创建div，例如：
echo“Description:$this_Description；”
$pageTitle = 'Services';
$keyword = "Books a Party Hall and Room Rentals in Toronto";
$description = "Books a Party Hall and Room Rentals in Toronto. Halls rental for Events, Adult & Children's Birthday Parties, Photography, Wedding, Music and Fashion Show Shoots, Corporate Presentations, Baby Showers, Going Away and Engagement Parties."; 
include 'header.php';

<title><?php echo $pageTitle; ?></title>
<meta name="keywords" content="<?php echo $keyword; ?>">
<meta name="description" content="<?php echo $description; ?>">
