Hello World!!!
This is simple text email message.

--PHP-alt-<?PHP echo $random_hash; ?> 
Content-Type: text/html; charset="iso-8859-1"
Content-Transfer-Encoding: 7bit

<h2>Hello World!</h2>
<p>This is something with <b>HTML</b> formatting.</p>

--PHP-alt-<?PHP echo $random_hash; ?>--

--PHP-mixed-<?PHP echo $random_hash; ?> 
Content-Type: application/zip; name="attachment.zip" 
Content-Transfer-Encoding: base64 
Content-Disposition: attachment 

<?PHP echo $attachment; ?>
--PHP-mixed-<?PHP echo $random_hash; ?>--

<?PHP
//copy current buffer contents into $message variable and delete current output buffer
$message = ob_get_clean();
//send the email
$mail_sent = @mail( $to,$subject,$message,$headers );
//if the message is sent successfully print "Mail sent". Otherwise print "Mail Failed"
echo $mail_sent ? "Mail sent" : "Mail Failed"; 

?>

任何熟悉这样做的人我希望使用PHP mail()函数.
