$results in a WordPress Page ?

Hello!

in an external php/form page
users are requested to answer a question
after they fill it in
and click on ‘submit’
they are directed to a WordPress page

can I save this code (the form’s input) on a WordPress page ?

<?php

$results = ‘result.txt’;
$fp = fopen($results, “a”);

$QA = $_POST[‘QA’];
$space = “/”;

fputs($fp,”\n”);
fputs($fp, $QA);
fputs($fp, $space);

fclose($fp);
?>
