Has anyone written a mail program with an attachment in the Mail class of pear mail? Can you give me an example?
Using the mail.php in pear
Require_once '/var/php/lib/php/mail.php ';

$conf [' mail '] = Array (
' Host ' = ' 163.com ',//SMTP server address, can use IP address or domain name
' Auth ' = True,//true indicates that the SMTP server requires authentication, and false code does not require
' username ' = ' abc ',//user name
' Password ' = ' abc '//Password
);

/***
* Using the $headers array, you can define the contents of the message header, such as using $headers[' reply-to '] to define the reply address
* In this way, it is easy to customize the message header for outgoing mail
***/
$headers [' from '] = ' [email protected] '; Sending address
$headers [' to '] = [email protected]; Delivery address
$headers [' Subject '] = ' hello,everyone '; Message header
$mail _object = &mail::factory (' smtp ', $conf [' Mail ']);

$body = "haha. I did it!!!! "; Message body

$mail _res = $mail _object-> Send ($headers [' to '], $headers, $body); Send

if (Pear::iserror ($mail _res)) {//Detect error
Die ($mail _res-> getMessage ());
} else {
echo "Send successful!";
}
?>

I use the above to send success, but if there are attachments do not know how to do, you heroes help me to see
