How can PHP be used to handle links within HTML files that are stored in a database and need to be followed for further navigation?

When HTML files are stored in a database and contain links that need to be followed for further navigation, PHP can be used to retrieve the HTML content from the database, parse the links, and handle the navigation accordingly. This can be achieved by using PHP's database connection functions to retrieve the HTML content, then using DOMDocument or regular expressions to extract and modify the links as needed for navigation. 

<?php
// Assuming $htmlContent contains the HTML content retrieved from the database

$dom = new DOMDocument();
$dom->loadHTML($htmlContent);

$links = $dom->getElementsByTagName('a');
foreach ($links as $link) {
    $href = $link->getAttribute('href');
    
    // Handle the link navigation as needed
    // For example, you can redirect the user to the link using header('Location: ' . $href);
}

// Output the modified HTML content
echo $dom->saveHTML();
?>
