Ruby to PHP AES

Im trying to convert some ruby code that encrypts data with AES 265 in CBC mode to php but its not working, the converted php code returns a null string. Here is what i have:

Ruby:

require 'openssl'

module AESCrypt
  def self.encrypt(message, password)
    Base64.encode64(self.encrypt_data(message.to_s.strip, self.key_digest(password), nil, "AES-256-CBC"))
  end

  def self.decrypt(message, password)
    base64_decoded = Base64.decode64(message.to_s.strip)
    self.decrypt_data(base64_decoded, self.key_digest(password), nil, "AES-256-CBC")
  end

  def self.key_digest(password)
    OpenSSL::Digest::SHA256.new(password).digest
  end

def self.decrypt_data(encrypted_data, key, iv, cipher_type)
    aes = OpenSSL::Cipher::Cipher.new(cipher_type)
    aes.decrypt
    aes.key = key
    aes.iv = iv if iv != nil
    aes.update(encrypted_data) + aes.final  
  end

def self.encrypt_data(data, key, iv, cipher_type)
    aes = OpenSSL::Cipher::Cipher.new(cipher_type)
    aes.encrypt
    aes.key = key
    aes.iv = iv if iv != nil
    aes.update(data) + aes.final      
  end
end

And the php code:

echo base64_encode($encrypted_data = mcrypt_encrypt(MCRYPT_RIJNDAEL_128, hash('sha256', 'p4ssw0rd'), 'hey', MCRYPT_MODE_CBC));

have a look at

https://github.com/nirnanaaa/xlix/blob/master/xlix/lib/Xlix/Bundle/Crypto/Aes/TwoLevel.php

I wrote this a while ago for my crypto functions based on a GIST I have found on the web
