Usage:

Copy code The code is as follows:

Include “email.class”

$mail->setTo("a@a.com"); //Recipient
$mail -> setCC("b@b.com,c@c.com"); //CC
$mail-> setCC("d@b.com,e@c.com"); / /Secret CC
$mail->setFrom(“f@f.com”);//Sender
$mail->setSubject(“Subject”); //Subject
$ mail->setText("text format");//Sending text format can also be a variable
$mail->setHTML("html format");//Sending html format can also be a variable
$ mail->setAttachments("c:a.jpg"); //Add attachments, need to indicate the path
$mail->send(); //Send mail
?>
