How can PHP developers ensure the security of login systems to prevent data interception by malicious parties?

To ensure the security of login systems and prevent data interception by malicious parties, PHP developers can implement secure password hashing using functions like password_hash() and password_verify(). Additionally, they should use HTTPS to encrypt data transmission between the client and server. 

// Hashing the password before storing it in the database
$password = $_POST['password'];
$hashed_password = password_hash($password, PASSWORD_DEFAULT);

// Verifying the password during login
$login_password = $_POST['login_password'];
$stored_hash = // retrieve hashed password from the database based on the username
if (password_verify($login_password, $stored_hash)) {
    // Password is correct
} else {
    // Password is incorrect
}
