PHP标头 - 每页添加不同的元标记

Question

I have a commom php header. I would like to add page specific META.

Currently my header looks like this.

<?php include ('includes/pageheader.php'); ?>

It currently uses a long if statemment

<?php $page =  $_SERVER['REQUEST_URI']; 
if($page == "/") {
  ?>
<!-- Metadata for home -->
?>

I was wondering if there was a better way or a class to be able to build up page specific meta to this header.

In your header, you could do something like this.

<?php if(isset($header)): ?>
  <?php foreach($header as $tag): ?>
    <?= $tag ?>
  <?php endforeach ?>
<?php endif ?>

Then above your include, you could add.

<?php
$header[] = '<meta charset="UTF-8">';
$header[] = '<meta name="description" content="Free Web tutorials">';
$header[] = '<meta name="keywords" content="HTML,CSS,XML,JavaScript">';
$header[] = '<meta name="author" content="John Doe">';
$header[] = '<meta name="viewport" content="width=device-width, initial-scale=1.0">';
include ('includes/pageheader.php');
?>
