You perform a fdopen() in C where you have a low level file descriptor and
make it a stdio on. In php there's only one kind of file descriptor, and 
all file
functions work with them.

Creating a fdopen call is useless, since it needs a previous descriptor to
work from, and all descriptors are equal. Where's that file descriptor 
coming
from?
Since it's an RPC server I suspect you will create it somehow with 
fsockopen.
