Sending Email with attachment remotely hosted

Hello,

I am trying to send an email using PHP with an attachment thats remotely hosted. I am trying the following script but it does not work with remote attachment but works with attachment with relative path i.e. file existing in the same directory. Can someone please tell me whats wrong in this script?


<?php
$fileatt = "http://www.freewebs.com/greenalternatives/chickureport_dahanu.PDF"; // Path to the file
$fileatt_type = "application/pdf"; // File Type
$fileatt_name = "chickureport_dahanu.PDF"; // Filename that will be used for the file as the attachment

$email_from = "me@mydomain.net"; // Who the email is from
$email_subject = "Your attached file"; // The Subject of the email
$email_message = "Thanks for visiting mysite.com! Here is your free file.
";
$email_message .= "Thanks for visiting.
"; // Message that the email has in it

$email_to = 'you@yourdomain.com'; // Who the email is to

$headers = "From: ".$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";

$headers .= "\
MIME-Version: 1.0\
" .
"Content-Type: multipart/mixed;\
" .
" boundary=\\"{$mime_boundary}\\"";

$email_message .= "This is a multi-part message in MIME format.\
\
" .
"--{$mime_boundary}\
" .
"Content-Type:text/html; charset=\\"iso-8859-1\\"\
" .
"Content-Transfer-Encoding: 7bit\
\
" .
$email_message .= "\
\
";

$data = chunk_split(base64_encode($data));

$email_message .= "--{$mime_boundary}\
" .
"Content-Type: {$fileatt_type};\
" .
" name=\\"{$fileatt_name}\\"\
" .
//"Content-Disposition: attachment;\
" .
//" filename=\\"{$fileatt_name}\\"\
" .
"Content-Transfer-Encoding: base64\
\
" .
$data .= "\
\
" .
"--{$mime_boundary}--\
";

$ok = @mail($email_to, $email_subject, $email_message, $headers);

if($ok) {
echo "You file has been sent
to the email address you specified.

Make sure to check your junk mail!

Click here to return to mysite.com.";

} else {
die("Sorry but the email could not be sent. Please go back and try again!");
}
