i want my script to die() if executed via http

[sneakyimp]

i want my script to die if someone tries to access it using http. i want it to run happily if executed via CLI or cron or call from [man]system[/man], [man]exec[/man] or [man]passthru[/man] within a page that is accessed using http.

I'm guessing that checking $SERVER might be a good way to do this but I'm not sure which value is a reliable indicator of someone accessing my script directly in a browser. maybe $SERVER['argc'] ?

I would check the port number too. If it's 80 or 443, then it's http(s).

Personally I'd have a look at $_SERVER['SERVER_SOFTWARE'] or something similar, which will always be set if you're invoked from the web, and never set if run from the CLI.

I've had a requirement to do this in the past, and just wrote a function IsInWeb()
