[thelist] [PHP] emailing an attachment

You need to use a MIME extension class to get this to work
right.

I've pasted one I use below. I didn't find any credit information
but I believe it came from the Wrox Programming PHP book.

This code should help you get it working. $filehandle is a pointer
to a file, either read from the drive or uploaded from a user.

include ("mime_mail.inc");
$mail = new mime_mail;

$content_type = "application/octet-stream";

$mail->from = $from_email;
$mail->to = $to_email;
$mail->subject = $subject;
$mail->body = $msg;
$mail->add_attachment($filehandle, "name of file", $content_type);
$mail->send();

Hope that helps,
