How does the placement of PHP code within HTML affect the performance and rendering in web browsers?

Placing PHP code at the top of an HTML file can slow down the rendering process in web browsers because the PHP code needs to be processed before the HTML is rendered. To improve performance, it is recommended to place PHP code at the bottom of the HTML file so that the HTML content can be rendered first. 

<!DOCTYPE html>
<html>
<head>
    <title>Example Page</title>
</head>
<body>
    <h1>Welcome to our website!</h1>
    
    <!-- HTML content goes here -->
    
    <?php
        // PHP code goes here
    ?>
</body>
</html>
