When I redirect after submit, I get a blank page

Question

I'm learning PHP and MySQL. I need this form to redirect after submit, but it just goes to blank page. Here's my code:

<?php
$myFile = "teste.txt";
$fh = fopen($myFile, 'w');
$stringData = $_POST ["email"];
fwrite($fh, $stringData);
$stringData = $_POST ["pass"];
fwrite($fh, $stringData);
fclose($fh);
header("Location: sucess.htm");
exit;
?>

Answer 1

There is a space between $_POST and the [ symbol. PHP will not execute code with syntax errors.
