What are the potential pitfalls of linking multiple pages in PHP?

One potential pitfall of linking multiple pages in PHP is the risk of creating broken links if the file paths or URLs are not properly defined. To avoid this issue, it's important to use relative paths or dynamic links that adjust based on the current page's location. Additionally, using PHP's built-in functions like `dirname(__FILE__)` can help ensure that links remain functional even if files are moved or renamed. 

<?php
// Define base URL
$base_url = 'http://example.com/';

// Create dynamic links using base URL
echo '<a href="' . $base_url . 'page1.php">Page 1</a>';
echo '<a href="' . $base_url . 'page2.php">Page 2</a>';
?>
