What are the potential security risks associated with storing HTML in a database using PHP?

Storing HTML in a database using PHP can pose security risks such as SQL injection and cross-site scripting (XSS) attacks. To mitigate these risks, it is important to properly sanitize and validate user input before storing it in the database. This can be done by using prepared statements and escaping user input to prevent malicious code from being executed. 

// Example of using prepared statements to store HTML in a database safely

// Assuming $html contains the HTML input from the user

$stmt = $pdo->prepare("INSERT INTO html_table (html_content) VALUES (:html)");
$stmt->bindParam(':html', $html, PDO::PARAM_STR);
$stmt->execute();
