You are right Bruno Rafael. I am willing to know the type of
application sending request to the server to run a PHP script (i think
it should be clear to all other ones that i am not asking for how
script will run on client side.)

As you have specified, if the request has been sent through command
line, $argc & $arv will exists whether having any values or not but
since we can access these values from $_SERVER (or $_ENV not sure
about it) which itself is an array, not set $_SERVER['argc'] is
equivalent to null $_SERVER['argc'], accessing the $_SERVER['argc']
will result to null values in both cases, then how one can distinguish
these cases?
