C# to PHP base64 encode/decode

​​http://stackoverflow.com/questions/257462/c-sharp-to-php-base64-encode-decode​​

We should probably URL Encode your Base64 string on the C# side before you send it.

And URL Decode it on the php side prior to base64 decoding it.

C# side

byte[] encbuff = System.Text.Encoding.UTF8.GetBytes("the string");
string enc = Convert.ToBase64String(encbuff);
string urlenc = Server.UrlEncode(enc);

and php side:

$data = $_REQUEST['in'];
$decdata = urldecode($data);
$raw = base64_decode($decdata);
