What potential pitfalls should beginners be aware of when integrating HTML and PHP code for dynamic content display?
Beginners should be aware of the potential pitfalls of mixing HTML and PHP code, such as syntax errors, security vulnerabilities, and difficulty in debugging. To avoid these issues, it is important to properly separate PHP logic from HTML presentation by using PHP opening and closing tags within the HTML code.
<?php
// PHP code here
?>
<!DOCTYPE html>
<html>
<head>
<title>Dynamic Content Display</title>
</head>
<body>
<h1>Welcome, <?php echo $username; ?></h1>
</body>
</html>
