In what ways can PHP developers ensure the security and integrity of user login data during transmission and storage?

To ensure the security and integrity of user login data during transmission and storage, PHP developers can implement secure communication protocols like HTTPS for data transmission and use encryption techniques like bcrypt for storing passwords securely. Additionally, developers should sanitize user inputs to prevent SQL injection attacks and use prepared statements to interact with the database securely. 

// Example of using bcrypt for password hashing
$password = "user_password";
$hashed_password = password_hash($password, PASSWORD_DEFAULT);

// Example of using prepared statements to interact with the database securely
$stmt = $pdo->prepare("SELECT * FROM users WHERE username = ?");
$stmt->execute([$username]);
$user = $stmt->fetch();
