如何将c＃函数转换为php

Question

How do I convert a C# function to a PHP function? The C# code is below:

internal string EncodePassword(string password, string salt)
{
       // Get the Unicode bytes of the plain text password.
       byte[] bytes = System.Text.Encoding.Unicode.GetBytes(password);

       // The salt is a Base64 encoded string, convert back to a byte array.
       byte[] src = Convert.FromBase64String(salt);

       // Concat both byte buffers.
       byte[] dst = new byte[src.Length + bytes.Length];
       byte[] inArray = null;
       System.Buffer.BlockCopy(src, 0, dst, 0, src.Length);
       System.Buffer.BlockCopy(bytes, 0, dst, src.Length, bytes.Length);

       // Compute the SHA1-hash from the concatenated buffer.
       System.Security.Cryptography.SHA1 algorithm = System.Security.Cryptography.SHA1Managed.Create();
       inArray = algorithm.ComputeHash(dst);

       // Return the result as a Base64-string.
       return Convert.ToBase64String(inArray);
}

I'd say it's something like this:

function encodePassword($password, $salt){
  return base64_encode(sha1($password . base64_decode($salt), true));
}
