Define values for checkbox answer – PHP

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?

    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

    This is what I’ve tried, I don’t know if it solves your question…

    
if(isset($_GET['answer']))
{
    echo "Answer is correct.";
    // more details here
}
else
{
    echo "Answer is incorrect.";
}


?>

<form action="/" method="GET">
    
    <label for="answer">
        <input type="checkbox" name="answer" id="lol" onchange="this.form.submit()" <?=$_GET['answer'] == "on" ? "checked" : ""?>>
        Correct?
    </label>
</form>
