从C＃到PHP的DES加密

Question

I am trying to port an encryption algorithm from C# to PHP. I know that the cipher mode is CBC and the encryption algorithm DES The initialization vector (IV) is

private static byte[] IV = { 38, 55, 206, 48, 28, 64, 20, 16 };

My problem is how the above IV, would be translated in php code?

My php code looks like this

$iv = ?;

mcrypt_encrypt(MCRYPT_DES, $key, $msg, MCRYPT_MODE_CBC, $iv);

Thanks

Use pack

$iv = pack('C*', 38, 55, 206, 48, 28, 64, 20, 16);
