TIA,
Carl,
It would appear that you require a basic PHP tutorial. $_SERVER is an
array populated by the server that deals with the php request, and as
such and explanation of such should not appear in any notes for any
3rd party scripts such as recaptcha.
> Where is the "recaptcha_challenge_field" located?
Again, a basic PHP tutorial would serve you. $_POST is an array
containing all the POSTed variables from the previous request, and is
not specific to recaptcha. $_GET is a similar array used for passing
in the GET variables.
If that previous sentence does not make sense, you do not know enough
PHP to make use of the recaptcha examples.

The recaptcha 'tutorials' are in no way a substitution for not
bothering to learn the basics of PHP. I suggest you google for some
basic tutorials dealing with these common concepts before trying to
jump in at the deep end, as it were.
