What are the potential pitfalls of storing HTML code in a database when generating dynamic content in PHP?

Storing HTML code in a database can lead to security vulnerabilities such as SQL injection and cross-site scripting attacks. To mitigate these risks, it is recommended to use prepared statements and data validation when retrieving HTML content from the database. 

// Example of using prepared statements to retrieve HTML content from the database

// Assuming $db is your database connection

// Prepare the SQL statement
$stmt = $db->prepare("SELECT html_content FROM pages WHERE id = ?");
$stmt->bind_param("i", $pageId);

// Set the page ID
$pageId = 1;

// Execute the query
$stmt->execute();

// Bind the result to a variable
$stmt->bind_result($htmlContent);

// Fetch the result
$stmt->fetch();

// Output the HTML content
echo $htmlContent;

// Close the statement
$stmt->close();
