What are the potential pitfalls of embedding HTML code within PHP tags?

Embedding HTML code within PHP tags can make the code harder to read and maintain, as it mixes presentation with logic. It can also lead to errors if not properly escaped or formatted. To solve this issue, it's recommended to separate the HTML code from the PHP logic by using alternative syntax like HEREDOC or NOWDOC for multi-line strings, or by using PHP echo statements to output HTML. 

<?php
// Example of separating HTML from PHP logic using echo statements
?>
<!DOCTYPE html>
<html>
<head>
    <title>Example Page</title>
</head>
<body>
    <h1><?php echo "Hello, World!"; ?></h1>
</body>
</html>
