    This will do the trick for you

    $checked_count = count($_POST['check_list']);
    $productlist = ''; //initialize an empty string for product list
    if ($checked_count > 1) //check if multiple check-boxes are checked
    { 
        $productlist = implode(', ', $_POST['check_list']); //implode all checkbox values in list string
        if(in_array('Others', $_POST['check_list'])) { //check if others is checked
            $productlist .= ', '.$_POST['otherproduct']; //con-cat text in text box lined with others in list string 
            $productlist = str_replace('Others,', '', $productlist); //remove others from the list string (skip if you want others to be in your result'
        }
    } elseif ($checked_count == 1) {
        $productlist = ($_POST['check_list'][0] == 'Others') ? $_POST['otherproduct'] : $_POST['check_list'][0]; //if only one checkbox is checked then check its value and use the value
    }
    echo "<br/>".$productlist;
    

    Additionally you may put client side and server side validations to be ensure that you get correct input values from your form.

    Also you can use java script to make your form more interactive.
