sending attachments via mail(), possible?

Is it possible to send attachments via mail() function? I tried it, and it didn't work out... the email I receive is all messed up, and even the simple text part of it is screwed up. I now very little about MIME, but I really need to send an attachment, any help? It's a text attachment... This is the code I'm using: function send_email($body,$num_pedido,$filename) { define(NL,"\n"); $boundary="test".chr(rand(65,91))."----".md5(uniqid(rand())); $message="Segue em anexo dados referentes ao pedido $num_pedido.".NL.NL; $message="Content-type: text/plain\nContent-transfer-encoding: 7bit".NL.NL.$message; $attach="Content-type: text/plain\nContent-transfer-encoding: base64\nContent-disposition: attachment; filename=".$filename.NL.NL; $attach.=base64_encode($body); $attach.=NL; $mail_body=$boundary.NL.$message.$boundary.NL.$attach.$boundary."-"; $header="MIME-Version: 1.0\nContent-Type: multipart/mixed;\n\tboundary=\"".$boundary."\"\nContent-Transfer-Encoding: 7bit"; // echo "<pre>$mail_body</pre>"; mail("christian@webstyle.com.br","CDYOU Pedido: ".$num_pedido,$mail_body,$header); } the headers are sent perfectly... and if I echo the $mail_body (I think) it's correct, but when I get the mail it's all screwed up... thanks... _________________________________ .
