Are there any potential security risks in updating the database directly with user input in PHP?

Directly updating the database with user input in PHP can pose security risks such as SQL injection attacks. To mitigate this risk, it is recommended to use prepared statements with parameterized queries to sanitize and validate user input before executing any database operations. 

// Example of using prepared statements to update the database with user input
$stmt = $pdo->prepare("UPDATE users SET email = :email WHERE id = :id");
$stmt->bindParam(':email', $email);
$stmt->bindParam(':id', $id);

$email = $_POST['email'];
$id = $_POST['id'];

$stmt->execute();
