Use a checkbox to define $var?

Newbie question: Is there a way to have an checkbox input define a
var?
I have a report for sales activity for a user definable date range.
>
I want to include a "Last Month" checkbox in my form section of the
page.
I already have the code to create the dates for this, but am hoping to
use an IF/ELSE with the checkbox to automatically populate the input
text boxes IF the box is checked.

Any common or creative ways to achieve this?

What you can do is something like:

if (isset($_POST['mycheckbox'])) {

assuming the form is POSTed to the server and the checkbox is named
'mycheckbox', of course.

You can even take this one further:

if (isset($_POST['mycheckbox']) && $_POST['mycheckbox'] = 'myvalue') {

This not only tests to see if the checkbox is set, but verifies the
value in the checkbox is 'myvalue'.

What about prior to the form getting submitted (no $_POST data yet)?
Can we do this in PHP, or would I have to look for some other
solution?

I'm kinda thinking along the lines of those "Yes, I agree to terms and
conditions" type checkboxes which, just by clicking them, do something
(such as enable/disable submit button).
