Define values for checkbox answer

Question

I'm trying to make a simple contact form, but I have difficulty to understand how checkbox works. This is the part I have a problem:

HTML:

<input name="selection" type="checkbox">

PHP:

$selection = $_POST['selection'];
$mail->Body = "
    Answer is ".$_POST["selection"]."
"

Once the checkbox is clicked and the form is submitted, the function above prints "Answer is on" in the e-mail. How can I print "Answer is Positive" once checkbox is clicked, and "Answer is Negative" when checkbox is not clicked in a simple way?

`$selection = isset($_POST['selection']) ? "Positive" : "Negative";` — Randommm, Mar 03 '23 at 13:10

Alright, I didn't know that defining a custom positive value for a checkbox is so simple:

HTML

<input name="selection" type="checkbox" value="Write here what you want to post when the checkbox is checked">

As for posting the negative value, I realized that it's not that necessary for my project. For those who wonder how, all alternatives are explained here:

POST unchecked HTML checkboxes
