What are the potential pitfalls of saving HTML content in a database using PHP?

One potential pitfall of saving HTML content in a database using PHP is the risk of SQL injection attacks if the input is not properly sanitized. To prevent this, you should use prepared statements with parameterized queries to securely insert the HTML content into the database. 

// Establish a database connection
$pdo = new PDO('mysql:host=localhost;dbname=your_database', 'username', 'password');

// Prepare a SQL statement with a parameterized query
$stmt = $pdo->prepare("INSERT INTO your_table (html_content) VALUES (:html_content)");

// Bind the HTML content to the parameter
$stmt->bindParam(':html_content', $html_content);

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