How can PHP developers ensure that sensitive user data, such as passwords, are securely stored and managed in databases?

To ensure that sensitive user data, such as passwords, are securely stored and managed in databases, PHP developers should hash the passwords before storing them. This means converting the password into a fixed-length string of characters using a hashing algorithm, such as bcrypt, which is designed to be slow and resistant to brute force attacks. Additionally, developers should also use prepared statements or parameterized queries to prevent SQL injection attacks. 

// Hashing and storing a user's password securely
$hashed_password = password_hash($user_input_password, PASSWORD_BCRYPT);

// Storing the hashed password in the database
$stmt = $pdo->prepare("INSERT INTO users (username, password) VALUES (:username, :password)");
$stmt->bindParam(':username', $username);
$stmt->bindParam(':password', $hashed_password);
$stmt->execute();
