Hi!,
I just out of curiosity want to know how top detect the client side
application under which the script is getting run. I mean to ask the
how to know whether the script is running under Command Prompt or
Browser or some other application?

Greetings, Jerry Stuckle.

As he said - if it is from the command line, $argc and $argv will exist,
as will $_SERVER['argc'] and $_SERVER['argv'].
Not if it is started using PHP-CGI and argc/argv vars disabled in
configuration.

If it's using php-cgi, then it's not started from the command line, is it?

then how one can distinguish these cases?
There's no need to. If the script is running from the command line, a
call to php_sapi_name() will return 'cli'.

Hi! all,
NC has provided a very useful point of using php_sapi_name to detect
the same. I tried to print 'PHP_SAPI' on my system and got the
following result:
Browser: apache2handler
Command Prompt: cli
I think it is of great help and we are going to have a robust
solution. Meanwhile, i would appreciate if anyone of you could share
the list of all possible php sapi (along with their possible
application from which they will be in existence).
And yes Jerry Stuckle do provided the good way of distinguish between
'not set element' and 'null element' inside the array. I was known to
it, but somehow it get slipped out of my mind.
Cheers! NC & Jerry Stuckle.
To continue the discussion, i would like to extend it a little bit
further by asking how to detect whether a request to the server has
been made directly or using sockets or using CURL from the client side
application?

No way to tell. This depends on the user agent sending information,
which is not reliable. For instance, depending on the site I'm
interfacing to in CURL, I might send some string such as "PHP-CURL", or
I might send the user agent the client is using (i.e. Firefox, IE, etc.).

Ok.
That's correct, but in case someone is wishing to deny the request
coming from the CURL or socket way, then what should be the procedure?

There is none. There is no way you can tell what the client is running,
other than what the client tells you. And that is not reliable.
The real question here is - what problem are you having?

As you said there is no way to track this, a spammer can develop a
script which will regularly send request to the web-server, forging
the original details??

Yep, when a php script is run from the commandline, the two variables
$argc and $argv (commandline arguments) are registered.
They might be empty, but they still would be registered when being run
from the commandline (and not when not in the commandline)

But that's server side. He asked about client side. And the answer is
there is no good way.
If the OP is trying to determine weather the program is running via a
internet server/browser or command line (terminal) then check this out.
Either of these two lines will tell you:
echo PHP_SAPI."\n\r" ;
or:
echo php_sapi_name() ."\n";
....see: http://us.php.net/manual/en/features.commandline.php
