How can developers ensure the security of user passwords when using md5 encryption in PHP?

Using md5 encryption for password hashing is not secure as it is vulnerable to various attacks such as rainbow table attacks. To ensure the security of user passwords, developers should use stronger encryption algorithms like bcrypt or Argon2. These algorithms are designed specifically for password hashing and include features like salting and key stretching to enhance security. 

$password = "user_password_here";
$hashed_password = password_hash($password, PASSWORD_BCRYPT);
