Hi
I wrote a class (PHPInvocation) that handles all the nitty gritty details of preparing NSURLRequests, NSURLConnections etc for calls to PHP scripts, but have run across this nasty bug. What's happening is that somewhere between the creation of an NSURLConnection and the target PHP script, "+" characters in base64 data get converted to spaces.

A '+' character is a shortcut for a space that you can use in the URI and Query parts of a URL. PHP will convert those for you. Which will happen on the server/php side.

If you want to send Base64 encoded data in a query parameter (or post data) then you will need to 'percentage-escape' it properly. In which case a '+' needs to be translated to a '+'.
