PHP code:

    <?php
        header('content-type:text/html;charset=utf-8');
        echo "<font size='24' face='Arial'>";//PHP放大字體
        $firstname = htmlspecialchars($_POST['firstname']);
        $lastname = $_POST['lastname'];
        $myfile = fopen("newfile.txt", "w") or die("Unable to open file!");
        fwrite($myfile, $lastname);
        fwrite($myfile, $firstname);
        fclose($myfile);
        echo 'OK';
    ?>
