There is nothing directly comparable to phpinfo() - much of what that function returns is PHP settings related to the web app integration components.

Here - I cooked this up for you:
# Intentionally not using /usr/bin/env python
# Why: /usr/local/bin is not passed to CGI scripts by a number of OS
# thus env would be unable to find python.

Its setup to be run as CGI but you can run that on the command line if you like just to see that it works. Comment out format_packages() if you don't like the delay as it goes through your system path.
