You can always check if the GET/POST item is set or not. If it is set then it's been checked, otherwise it's not been checked. An alternative would be to supply a hidden attribute before the check box. That way if the check box is not checked, the value will be taken from the hidden element, otherwise if it is checked, the priority ordering will consider the second element with the same name to be the correct one.

Something like the following:

html4strict Code:

<form method="get">

    <input type="hidden" name="TalkPHPCheckbox" value="0" />
    <input type="checkbox" name="TalkPHPCheckbox" value="1" />
    
    <input type="submit" />

</form>

And of course the PHP to go along with it:

php Code:

if(isset($_GET['TalkPHPCheckbox']))
{
    echo $_GET['TalkPHPCheckbox'] == 0 ? 'Off' : 'On';
}
