How can PHP code be properly integrated into an HTML form to prevent parsing errors?

To properly integrate PHP code into an HTML form and prevent parsing errors, you can use the PHP opening and closing tags within the form elements. This allows you to mix PHP code with HTML markup seamlessly. Make sure to escape any special characters or variables properly to avoid syntax errors. 

<form action="submit.php" method="post">
    <input type="text" name="username" value="<?php echo isset($_POST['username']) ? $_POST['username'] : ''; ?>">
    <input type="submit" value="Submit">
</form>
