How can PHP developers ensure the integrity of user password hashes in a MySQL database?

To ensure the integrity of user password hashes in a MySQL database, PHP developers should use a strong hashing algorithm, such as bcrypt, to securely hash and store passwords. Additionally, they should salt the passwords before hashing to add an extra layer of security. Finally, developers should regularly update their hashing methods to stay ahead of potential security threats. 

$password = "user_password";
$salt = openssl_random_pseudo_bytes(16); // Generate a random salt
$hashed_password = password_hash($password, PASSWORD_BCRYPT, ['salt' => $salt]); // Hash the password with bcrypt and the salt

// Store $hashed_password and $salt in the MySQL database
