What are the potential issues that arise when handling HTML content in PHP, especially when it is stored in a database?

Issue: One potential issue when handling HTML content in PHP, especially when stored in a database, is the risk of SQL injection attacks if the HTML content is not properly sanitized. To mitigate this risk, it is important to use prepared statements or parameterized queries when interacting with the database to prevent malicious SQL code from being executed. 

// Using prepared statements to handle HTML content in PHP when interacting with a database
$stmt = $pdo->prepare("INSERT INTO table_name (html_content) VALUES (:html_content)");
$stmt->bindParam(':html_content', $html_content);
$stmt->execute();
