CGI/command line

Hey, I'm using the CGI version to handle some backend management to a site, like sending mail queues and processing information so the web client doesnt block. I have a few questions and the CGI binary... How can I detect that the CGI version is running, opposed to the apache one? I saw the SAPI in phpinfo(), but I cant seem to extract that cleanly to do the test. And also, -d on the command line (trying -d include_path="/home/blah/include/") doesnt seem to work. Using the latest CVS. Thanks. -d -- (void *)0
