How can PHP developers ensure the integrity of password hashing and storage in databases when using MD5 encryption?

When using MD5 encryption for password hashing and storage in databases, PHP developers can ensure integrity by salting the passwords before hashing them. This involves adding a unique random string (salt) to each password before hashing, making it more secure against attacks like rainbow tables. Additionally, developers should consider using stronger hashing algorithms like bcrypt or Argon2 for better security. 

// Function to securely hash and salt passwords using MD5
function hashPassword($password) {
    $salt = uniqid(mt_rand(), true);
    $hashedPassword = md5($salt . $password);
    
    return array('salt' => $salt, 'hashedPassword' => $hashedPassword);
}

// Example of hashing and storing a password
$password = "password123";
$hashedData = hashPassword($password);

// Store $hashedData['salt'] and $hashedData['hashedPassword'] in the database
