PHP PDF attachment

Can anyone help. I have code which will send email with an attachment via PHP however when it arrives to the destination email the PDF file is empty. I have come across a few emails where people have had the same problem but no answers. Any ideas? Using the normal mail() function with the code below: $to = $email; $from = "info@webpage.co.uk"; $subject = "Thank you for downloading the document"; $message = "Dear $username,<br> Thank you for taking the time to subscribe for our free document.<br> Please find the document attached to this email."; // Obtain file upload vars $fileatt = "db/"; // Location of file on server $fileatt_type = "application/pdf";// Type of file being sent $fileatt_name = "webopman.pdf";// Name of file $headers = "From: $from"; // If the file exists... if (file_exists($fileatt)) { // Read the file to be attached ('rb' = read binary) $file = fopen($fileatt,'rb'); $data = fread($file,filesize($fileatt)); fclose($file); // Generate a boundary string $semi_rand = md5(time()); $mime_boundary = "==Multipart_Boundary_x{$semi_rand}x"; // Add the headers for a file attachment $headers .= "\nMIME-Version: 1.0\n" . "Content-Type: multipart/mixed;\n" . " boundary=\"{$mime_boundary}\""; // Add a multipart boundary above the plain message $message = "This is a multi-part message in MIME format.\n\n" . "--{$mime_boundary}\n" . "Content-Type: text/html; charset=\"iso-8859-1\"\n" . "Content-Transfer-Encoding: 7bit\n\n" . $message . "\n\n"; // Base64 encode the file data $data = chunk_split(base64_encode($data)); // Add file attachment to the message $message .= "--{$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"; } $ok = @mail($to, $subject, $message, $headers); Real stuck here.
