Implementing fdopen in PHP

Hi all, It's my first post, so go easy on me. :-) I'm trying to implement PHP support for github's erlang RPC server called ernie. So basically I've been porting the following ruby code to PHP: http://github.com/mojombo/ernie/blob/master/lib/ernie.rb The problem I'm having is on line 127-128: input = IO.new(3) I believe this is equivalent to fdopen() in C, but there doesn't appear to be any way to do this in PHP. So basically, I'm a bit stuck and looking for advice on how to proceed. Should I implement this in core PHP or as an extension? What's the best way to get a function like this into PHP?
