php-mail со вложением

Я выполнил функцию php mail для отправки почты с вложением, но я получаю почту с приложением 0 kb. Код, который я использую ниже:

<?php $fileatt = ""; // Path to the file $fileatt_type = "application/octet-stream"; // File Type $fileatt_name = ""; // Filename that will be used for the file as the attachment $email_from = ""; // Who the email is from $email_subject = ""; // The Subject of the email $email_txt = ""; // Message that the email has in it $email_to = ""; // Who the email is too $headers = "From: ".$email_from; $file = fopen($fileatt,'rb'); $data = fread($file,filesize($fileatt)); fclose($file); $semi_rand = md5(time()); $mime_boundary = "==Multipart_Boundary_x{$semi_rand}x"; $headers .= "\nMIME-Version: 1.0\n" . "Content-Type: multipart/mixed;\n" . " boundary=\"{$mime_boundary}\""; $email_message .= "This is a multi-part message in MIME format.\n\n" . "--{$mime_boundary}\n" . "Content-Type:text/html; charset=\"iso-8859-1\"\n" . "Content-Transfer-Encoding: 7bit\n\n" . $email_message . "\n\n"; $data = chunk_split(base64_encode($data)); $email_message .= "--{$mime_boundary}\n" . "Content-Type: {$fileatt_type};\n" . " name=\"{$fileatt_name}\"\n" . //"Content-Disposition: attachment;\n" . //" filename=\"{$fileatt_name}\"\n" . "Content-Transfer-Encoding: base64\n\n" . $data . "\n\n" . "--{$mime_boundary}--\n"; $ok = @mail($email_to, $email_subject, $email_message, $headers); if($ok) { echo "<font face=verdana size=2>The file was successfully sent!</font>"; } else { die("Sorry but the email could not be sent. Please go back and try again!"); } ?> 

Я не могу понять проблему с этим кодом. Пожалуйста, помогите мне!
