What are some potential drawbacks of including meta tags in individual PHP files for each content page?

Including meta tags in individual PHP files for each content page can lead to duplication of code and make it difficult to maintain consistency across the site. To solve this issue, a better approach would be to centralize the meta tag information in a separate file and include it in each content page as needed. 

// meta_tags.php

<?php
$meta_title = "Page Title";
$meta_description = "Page Description";
$meta_keywords = "keyword1, keyword2, keyword3";
?>


// content_page.php

<?php
include 'meta_tags.php';
?>

<!DOCTYPE html>
<html>
<head>
    <title><?php echo $meta_title; ?></title>
    <meta name="description" content="<?php echo $meta_description; ?>">
    <meta name="keywords" content="<?php echo $meta_keywords; ?>">
</head>
<body>
    <!-- Content goes here -->
</body>
</html>
