What are the best practices for handling and displaying dynamic HTML content stored in a database using PHP?

When handling dynamic HTML content stored in a database using PHP, it is important to properly sanitize the data to prevent XSS attacks. One way to do this is by using the htmlentities() function to encode special characters. Additionally, it is recommended to use prepared statements when querying the database to prevent SQL injection attacks. 

// Retrieve dynamic HTML content from the database
$query = "SELECT html_content FROM dynamic_content WHERE id = ?";
$stmt = $pdo->prepare($query);
$stmt->execute([$id]);
$result = $stmt->fetch();

// Display the dynamic HTML content on the page
echo htmlentities($result['html_content']);
