Thanks, I don't need this for a real project, I am reading the book
Programming The Semantic Web where the examples are in Java and as I go
I try to implement the parts I can in PHP with arc as well.

In the past, I've tackled this in one of two ways...
If I know I'm going to want it in the ARC store, and if the file is
small enough, I've just copied it into ARC's endpoint with INSERT. Not
elegant, but does the job.
For general just querying around rdf files before I know I want them in
the store, I've often used Twinkle [1] . It's a java app that'll let
you query local files directly.
