What are common pitfalls when storing HTML code in a database in PHP?

One common pitfall when storing HTML code in a database in PHP is the risk of SQL injection attacks if the HTML code is not properly sanitized before insertion. To mitigate this risk, always use prepared statements with parameterized queries to insert HTML code into the database. This helps prevent malicious SQL injection attempts and ensures the security of your application. 

// Sample PHP code snippet to safely store HTML code in a database using prepared statements

// Assume $htmlCode contains the HTML code to be stored

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

// Prepare the SQL statement with a placeholder for the HTML code
$stmt = $pdo->prepare("INSERT INTO html_table (html_code) VALUES (:html)");

// Bind the HTML code parameter to the prepared statement
$stmt->bindParam(':html', $htmlCode);

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