??? When a form is submitted using
the GET method, you??™ll see the
form data in the URL, with

item=this_value&that_
item=that_value. This is the
same syntax used by POST, but
the data isn??™t sent in the URL
and you don??™t need the question
mark.
??? All of the form data needs to be
run through the encodeURIComponent()
function to make it safe
to send to the PHP page. Rather
than apply that function to each
value separately, using a for loop
on an array of form elements lets
us accomplish the same thing
with less code.

is used to perform concatenation:

another. In PHP, the period does
the same thing.
