In PHP how can I detect code is being run from command line

command-line-interface

When I run my PHP script from the command line I get the following notices. I assume the reason is that these variables such SERVER_NAME are not applicable when running without a browser.

In my code how can I detect that it is run from command line and skip those lines, so I dont have to see these notices?

I dont want to block these notices by piping to /dev/null, I would rather enhance the PHP code.

Check php_sapi_name(). If it =='cli', then you are calling from the command line.
