Parsing command-line arguments

OK, this may be a sick and twisted question, but I'd rather write the code once. :) What facilities are there in PHP for parsing command line arguments? And does it "know" how it's being invoked? I want to share a significant hunk of code between the compiled-into-apache code and some command line stuff. -- _Deirdre * http://www.sfknit.org * http://www.deirdre.net "We can always count on the British.
