How can the inclusion of HTML content in PHP files impact code readability and maintainability?

Including HTML content directly in PHP files can make the code harder to read and maintain as it mixes logic with presentation. To improve readability and maintainability, it is recommended to separate HTML content from PHP logic using a templating system or by using PHP's heredoc syntax to embed HTML content within the PHP code. 

<?php
// Example of separating HTML content from PHP logic using heredoc syntax

$htmlContent = <<<HTML
<!DOCTYPE html>
<html>
<head>
    <title>Hello World</title>
</head>
<body>
    <h1>Hello, World!</h1>
</body>
</html>
HTML;

echo $htmlContent;
?>
