What are the potential consequences of having multiple HTML head sections in a PHP script?

Having multiple HTML head sections in a PHP script can lead to invalid HTML markup and potentially cause rendering issues in the browser. To solve this issue, you can concatenate all the necessary head elements into a single head section within the PHP script.

<!DOCTYPE html>
<html>
<head>
    <title>Page Title</title>
    <?php
    // Other head elements can be dynamically generated here
    ?>
</head>
<body>
    <!-- Page content goes here -->
</body>
</html>
