How do I merge PHP file to attach and send multiple attachments with existing PHP file?

Any experts out there on PHP?

I am trying to merge the following php code (#2) with my existing php code (#1) so that it I can attach and send multiple files. I've got it so I can attach and send files, no problem, but the form verification and anti-bot test no longer works. I realize there might be some redundancies in the two php codes. I have removed, replaced and tried combining code multiple times, but to no avail. Also the code in #2 returns a blank page saying "Message sent" or "Failed to send" when I prefer what I already have in code #1 with the message appearing in a div over top of the page. 

Any guidance without starting from scratch with php mailers, etc, would be very appreciated. It's probably something simple for those of you well-versed in PHP.

Thanks!

PHP #1 (No file attachment, but form verification and anti-bot test):

<?php
// NOTE: this page must be saved as a .php file.
// And your server must support PHP 5.3+ PHP Mail().
// Define variables and set to empty values
$result = $message = $human = "";
$errName = $errMessage = $errHuman = "";
if ( isset( $_POST[ "submit" ] ) ) {
$message = $_POST[ 'message' ];
$human = intval( $_POST[ 'human' ] );
//valid address on your web server
$from = 'me@myemail.com';
//your email address where you wish to receive mail
$to = 'me@myemail.com';
$subject = 'MESSAGE FROM YOUR WEB SITE';
$headers = "From:$from\r\nReply-to:$email";
$body = "Message: $message";
//Check if message is entered
if ( empty( $_POST[ "message" ] ) ) {
$errMessage = "Please enter your message.";
} else {
$message = test_input( $_POST[ "message" ] );
}
//Check if simple anti-bot test is entered
if ( empty( $_POST[ "human" ] ) ) {
$errHuman = "Please enter the sum.";
} else {
if ( $human !== 1001 ) {
$errHuman = 'Wrong answer. Please try again.';
}
}
// If there are no errors, send the email & output results to the form
if ( !$errMessage && !$errHuman ) {
if ( mail( $to, $subject, $body, $from ) ) {
$result = '<div class="alert alert-success"><h2><span class="glyphicon glyphicon-ok"></span> Message sent!</h2><h3>Thank you for contacting us. Someone will be in touch with you soon.</h3></div>';
} else {
$result = '<div class="alert alert-danger"><h2><span class="glyphicon glyphicon-warning-sign"></span> Sorry there was a form processing error.</h2> <h3>Please try again later.</h3></div>';
}
}
}
//sanitize data inputs
function test_input( $data ) {
$data = trim( $data );
$data = stripslashes( $data );
$data = htmlspecialchars( $data );
$data = ( filter_var( $data, FILTER_SANITIZE_STRING ) );
return $data;
}
//end form processing script
?>

PHP #2 (Multiple file attachment):

<?php
if ($_SERVER['REQUEST_METHOD']=="POST"){

// we'll begin by assigning the To address and message subject
$to="me@myemail.com";
$subject="E-mail with attachment";

// get the sender's name and email address
// we'll just plug them a variable to be used later
$from = stripslashes($_POST['fromname'])."<".stripslashes($_POST['fromemail']).">";

// generate a random string to be used as the boundary marker
$mime_boundary="==Multipart_Boundary_x".md5(mt_rand())."x";

// now we'll build the message headers
$headers = "From: $from\r\n" .
"MIME-Version: 1.0\r\n" .
"Content-Type: multipart/mixed;\r\n" .
" boundary=\"{$mime_boundary}\"";

// here, we'll start the message body.
// this is the text that will be displayed
// in the e-mail
$message="This is an example";

$message .= "Name:".$_POST["fromname"]."Message Posted:".$_POST["modlist"];

// next, we'll build the invisible portion of the message body
// note that we insert two dashes in front of the MIME boundary
// when we use it
$message = "This is a multi-part message in MIME format.\n\n" .
"--{$mime_boundary}\n" .
"Content-Type: text/plain; charset=\"iso-8859-1\"\n" .
"Content-Transfer-Encoding: 7bit\n\n" .
$message . "\n\n";

// now we'll process our uploaded files
foreach($_FILES as $userfile){
// store the file information to variables for easier access
$tmp_name = $userfile['tmp_name'];
$type = $userfile['type'];
$name = $userfile['name'];
$size = $userfile['size'];

// if the upload succeded, the file will exist
if (file_exists($tmp_name)){

// check to make sure that it is an uploaded file and not a system file
if(is_uploaded_file($tmp_name)){

// open the file for a binary read
$file = fopen($tmp_name,'rb');

// read the file content into a variable
$data = fread($file,filesize($tmp_name));

// close the file
fclose($file);

// now we encode it and split it into acceptable length lines
$data = chunk_split(base64_encode($data));
}

// now we'll insert a boundary to indicate we're starting the attachment
// we have to specify the content type, file name, and disposition as
// an attachment, then add the file content.
// NOTE: we don't set another boundary to indicate that the end of the
// file has been reached here. we only want one boundary between each file
// we'll add the final one after the loop finishes.
$message .= "--{$mime_boundary}\n" .
"Content-Type: {$type};\n" .
" name=\"{$name}\"\n" .
"Content-Disposition: attachment;\n" .
" filename=\"{$fileatt_name}\"\n" .
"Content-Transfer-Encoding: base64\n\n" .
$data . "\n\n";
}
}
// here's our closing mime boundary that indicates the last of the message
$message.="--{$mime_boundary}--\n";
// now we just send the message
if (@mail($to, $subject, $message, $headers))
echo "Message Sent";
else
echo "Failed to send";
} else {
?>
