What are some recommended approaches for integrating PHP code with HTML output to create dynamic and interactive web applications?

One recommended approach for integrating PHP code with HTML output is to use PHP's echo or print functions to output dynamic content within HTML tags. This allows for the seamless integration of PHP logic within the HTML structure, enabling the creation of dynamic and interactive web applications.

<!DOCTYPE html>
<html>
<head>
    <title>Dynamic Web Page</title>
</head>
<body>
    <h1>Welcome <?php echo "User"; ?></h1>
    <p>Today's date is <?php echo date("Y-m-d"); ?></p>
</body>
</html>
