Jorge: empty() will act in the same way as isset() with regards to indices not being set.
if (empty($_SERVER['non_existant'])) will not cause an error to be thrown.

$_SERVER['REMOTE_ADDR'] would throw a warning if it’s not set. Check to see if it exists before checking it’s value.

Either way, this was helpful, thanks!

Aren’t you also able to check the count of argc? If called from the command line, it will exist in the $_SERVER superglobal and its count will be at least one (the first item being the name of the file):

$using_cli = (@$_SERVER['argc'] >= 1);

Great! Thank you!
But i think we can make it shorter with this command:
return (php_sapi_name() == ‘cli’ && empty($_SERVER['REMOTE_ADDR']))
