PHP + binary files

I am persisting nested (tree) structures in C to binary file. I want to
be able to read/write this data using PHP - is this possible?. That is
to say, can PHP read/write C structures to file so that the contents may
be transferred to a C client app?

The idea is that I store the binary files at the server end and clients
can request for the file(s). Is this possible ?

PS- the client is (of course) a C++ client, capable of understanding the
returned structure. Another point worth mentioning is that the server
will be on Unix and the client on Windows. Can I force PHP to write the
binary file using Network byte order so that endianess is not an issue?
