How can PHP developers ensure the secure transmission of login data, especially in the context of password hashing?

To ensure the secure transmission of login data, especially in the context of password hashing, PHP developers should use HTTPS to encrypt the data in transit. This can be achieved by obtaining an SSL certificate for the website and configuring the server to use HTTPS. Additionally, developers should also implement secure password hashing techniques, such as using the password_hash() function in PHP, to securely store and verify passwords. 

// Enable HTTPS by redirecting HTTP requests to HTTPS
if ($_SERVER['HTTPS'] != 'on') {
    header('Location: https://' . $_SERVER['HTTP_HOST'] . $_SERVER['REQUEST_URI']);
    exit();
}

// Example of password hashing using password_hash() function
$password = 'secretPassword';
$hashedPassword = password_hash($password, PASSWORD_DEFAULT);

// Verify hashed password
if (password_verify($password, $hashedPassword)) {
    echo 'Password is valid!';
} else {
    echo 'Invalid password.';
}
