How can the order of HTML and PHP code affect the display of content on a webpage?

The order of HTML and PHP code can affect the display of content on a webpage because PHP code is executed server-side before the HTML is sent to the client's browser. If PHP code is placed after HTML content, it may not be executed in time to affect that content. To ensure proper display, PHP code that generates content should be placed before any HTML code that relies on that content. 

<?php
// PHP code to generate content
$content = "Hello, World!";
?>

<!DOCTYPE html>
<html>
<head>
    <title>Display Content</title>
</head>
<body>
    <p><?php echo $content; ?></p>
</body>
</html>
