What potential pitfalls should be considered when saving user-generated content in PHP?

One potential pitfall when saving user-generated content in PHP is the risk of SQL injection attacks if the input is not properly sanitized. To prevent this, always use prepared statements or parameterized queries when interacting with the database to ensure that user input is not executed as SQL code. 

// Example of using prepared statements to save user-generated content securely

// Assuming $conn is the database connection object

$userInput = $_POST['user_input'];

$stmt = $conn->prepare("INSERT INTO table_name (content) VALUES (?)");
$stmt->bind_param("s", $userInput);
$stmt->execute();
$stmt->close();
