Hello. this is really a stupid question and I believe there are tons of
answers on the Internet, but if I search I must use the keyword "[]"
which simply gets ignored by google.

Why I see a lot of people adding an empty [] after the variable name
used in <input> ? Is there a good reason?

After I did some rough test it seems to me submitting by GET can
generate more then one value for an variable:


however submtting by POST generate only one value for one name;


even if there are many <input name="varname" .../>, only the last value
is submitted.

Is this the only/real reason to use empty []?
