White screen of death on simple form

Get Started
1

Hi.

I’m creating a simple email form on a local development environment.
I’m testing it both locally and on a hostgator shared host.

Upon submitting the form, I’m getting the white screen. This happens on both environments

After some googling, I came across advice to turn on error reporting, either in the file or in php.ini.
So locally in my php file that processes the form,
I have pasted these lines:

ini_set('display_errors', 1); 
 error_reporting(E_ALL);

I have uncommented this line from my php.ini, before restarting apache:

error_reporting = E_ALL & ~E_NOTICE

Unfortunatly, this makes no difference. I’m still getting the white screen with no errors being reported.

How can I further diagnose the problem?
What is likely to be going wrong?

Here is a paste of my form processing code:

<?php

ini_set('display_errors', 1); 
 error_reporting(E_ALL);


// Mail header removal
function remove_headers($string) 
{ $headers = array( "/to\\:/i", "/from\\:/i", "/bcc\\:/i", "/cc\\:/i", 
		    "/Content\\-Transfer\\-Encoding\\:/i", 
		    "/Content\\-Type\\:/i", "/Mime\\-Version\\:/i" ); 
  $string = preg_replace($headers, '', $string); return strip_tags($string);
}

$name = remove_headers($_POST['name']);
$email = remove_headers($_POST['email']);
$subject = remove_headers($_POST['subject']);
$message = remove_headers($_POST['message']);

// Build the email (replace the address in the $to section with your own)
$to = "me@example.com";
$email = "New message: $subject";
$message = "$email said: $message";
$headers = "From: $email";

// Send the mail using PHPs mail() function
mail($to, $subject, $message, $headers);

?>

Have you checked the error logs?

If you try

// Send the mail using PHPs mail() function
if ( mail($to, $subject, $message, $headers) )
{
echo 'Mail Successful';
}
else
{
echo 'Mail Failed';
}
?>

Do you see mail Success or Fail or neither?
