What are some potential issues with the order of PHP code execution in HTML?

One potential issue with the order of PHP code execution in HTML is that PHP code needs to be executed before the HTML content is rendered by the browser. To solve this issue, you can place your PHP code at the top of your HTML file or use PHP opening and closing tags within the HTML content to ensure proper execution order.

<?php
// PHP code here
?>

<!DOCTYPE html>
<html>
<head>
    <title>Example</title>
</head>
<body>
    <h1><?php echo "Hello, World!"; ?></h1>
</body>
</html>
