How can constants be used to define meta content in PHP for dynamic pages?

To define meta content for dynamic pages in PHP, constants can be used to store values such as page titles, descriptions, and keywords. This allows for easy management and consistency across multiple pages. By defining these constants at the beginning of a PHP file, they can be easily accessed and echoed within the HTML meta tags. 

<?php
define('PAGE_TITLE', 'Dynamic Page Title');
define('META_DESCRIPTION', 'This is a dynamic page description');
define('META_KEYWORDS', 'dynamic, page, keywords');

// Include these constants in the HTML meta tags
echo "<title>" . PAGE_TITLE . "</title>";
echo "<meta name='description' content='" . META_DESCRIPTION . "'>";
echo "<meta name='keywords' content='" . META_KEYWORDS . "'>";
?>
