Emailing Uploaded attachments with PHP

I have a web application developed that is essentially a form that users fill out and upload and image. The php grabs the submission and emails it off to the client. Nothing is stored on the web server. Works great in our dev environment (of course) which is a windows box runing php 5.2.0 (CGI/FastCGI) but not the production environment. The production environment is a linux box,Apache 2.0 Handler, php 4.3.10.
Now in both environments the form works, users fill it out and upload their image. And in both environments the email is sent (see attachments for the source code of the sent emails - New1.txt is the dev environment - works, New2.txt is the live box - no worky). The dev environ email has the image attached with all the email body etc. as one would expect. The production box email is virtually identical in the source code but the image is not attached but rather streamed code in the body. Upgrading the php on the production box is NOT really an option there are a bunch of other sites and legacy code that I don't want to risk hosing.  Could it be an apache setting?
$sent=false;
if ($_SERVER['REQUEST_METHOD']=='POST') {
 //Validate construct error string
// Receiving variables
$f_name = addslashes($_POST['f_name']);
$l_name = addslashes($_POST['l_name']);
$story = addslashes($_POST['story']);
$email = addslashes($_POST['email']);
$spa_model = implode(", ",$_POST['spa_model']);
 
 if (strlen($f_name) <= 0)
 {
 $Error .= "<br />Please enter your 'First Name'\n";
 }
 if (strlen($l_name) <= 0)
 {
 $Error .= "<br />Please enter your 'Last Name'\n";
 }
 if ((strlen($email) != 0 ) && (! ereg('[A-Za-z0-9_-]+\@[A-Za-z0-9_-]+\.[A-Za-z0-9_-]+', $email)))
 {
 $Error .= "<br />Please enter a valid 'Email Address'\n";
 }
 
 if (strlen($email) == 0 )
 {
 $Error .= "<br />Please enter an 'Email Address'\n";
 }
 
 if (strlen($spa_model) <= 0)
 {
 $Error .= "<br />Please check at least one 'Spa' model\n";
 }
 
 
 if (strlen($story) <= 0)
 {
 $Error .= "<br />Please enter 'Your Story'\n";
 }
 
if (strlen($Error) <= 0) {
$tmp = $_FILES['userfile']['tmp_name'];
$sep = md5(time());
$filename = $_FILES['userfile']['name'];
$filedata = file_get_contents($tmp); //Get file contents
$fdata = chunk_split(base64_encode($filedata));   //Encoding all the data read from file to "base64" the standard for email attachments
$to = "dana.gray@gmail.com"; //Email address to send this to
//Determine mime type
$ext = explode('.', $filename);
$ext = $ext[1];
 
if($ext == "JPG" || $ext == "jpg" || $ext == "JPEG" || $ext == "jpeg") {
$mime_type = "image/jpeg";
}
elseif($ext == "gif" || $ext == "GIF") {
$mime_type = "image/gif";
}
elseif($ext == "bmp" || $ext == "BMP") {
$mime_type = "image/bmp"; //I think that's the mime type for BMP files
}
elseif($ext == "txt" || $ext == "TXT") {
$mime_type = "text/plain";
}
else {
//exit("Error: Wrong file type!");
}
// 
 
$subject = "Submission from Site";
 
  // Setting basic headers info
  $headers = "From: \"$f_name $l_name\" <{$email}>\n";
  
  //Making a random number to use afterwards with help of current time
  $semi_rand = md5( time() );
  
  //Defining the type of email as Mime email
  $mime_boundary = "==Multipart_Boundary_x{$semi_rand}x";
  
  //Appending to headers, telling that its multipart message with text and attachment
  $headers .= "\nMIME-Version: 1.0\n" .
    "Content-Type: multipart/mixed;\n" .
    " boundary=\"{$mime_boundary}\"";
  
  //The start of the message
  $message = "This is a multi-part message in MIME format.\n\n" .
    "--{$mime_boundary}\n" .
    "Content-Type: text/plain; charset=\"iso-8859-1\"\n" .
    "Content-Transfer-Encoding: 7bit\n\n";
  //Begin the text message. 
  $message .= " Submission information:\n"
	. "name: $f_name $l_name \n"
	. "email: $email\n"
	. "spa: $spa_model\n"
	. "story: $story\n";
 
  //Appending the file data to the email including the file name etc
  $message .= "--{$mime_boundary}\n" .
    "Content-Type: {$mime_type};\n" .
    " name=\"MyStory\"\n" .
    "Content-Disposition: attachment;\n" .
    " filename=\"{$filename}\"\n" .
    "Content-Transfer-Encoding: base64\n\n" .
    $fdata . "\n\n" .
    "--{$mime_boundary}--\n";
 
 
mail($to, $subject, $message, $headers);
//mail($to2, $subject, $message, $headers);

$sent=true;

Revised code to create temporary file and email that rather than reading contents directly from uploaded file. This works on Apache server. Not resolved as to why windows environment with php will perform as expected while apache environment does not.
