加密解密 - 用php实现java中的aes加密

java中的aes加密算法如下：

    public static byte[] decrypt(byte[] data, byte[] key)
            throws NoSuchPaddingException, NoSuchAlgorithmException, InvalidKeyException, BadPaddingException, IllegalBlockSizeException {
        Security.addProvider(new BouncyCastleProvider());
        Cipher cipher = Cipher.getInstance("AES/ECB/PKCS7Padding");
        cipher.init(2, new SecretKeySpec(key, "AES"));
        return cipher.doFinal(data);
    }

    public static byte[] encrypt(byte[] data, byte[] key)
            throws NoSuchPaddingException, NoSuchAlgorithmException, InvalidKeyException, BadPaddingException, IllegalBlockSizeException {
        Security.addProvider(new BouncyCastleProvider());
        Cipher cipher = Cipher.getInstance("AES/ECB/PKCS7Padding");
        cipher.init(1, new SecretKeySpec(key, "AES"));
        return cipher.doFinal(data);
    }

请问如何用php来实现
我测试了很多网上的例子都不能得到相同的密文
