What potential pitfalls should be considered when saving HTML content in a database with PHP?

One potential pitfall to consider when saving HTML content in a database with PHP is the risk of SQL injection attacks if the HTML content is not properly sanitized. To mitigate this risk, always use prepared statements with parameterized queries when inserting HTML content into the database. This helps prevent malicious SQL code from being executed. 

// Assuming $htmlContent contains the HTML content to be saved in the database

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

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

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

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