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 is also possible It is the variable
$mail->setHTML("html format");//Sending html format can also be the variable
$mail->setAttachments("c:a.jpg");//Add attachments , need to indicate the path
$mail->send(); //Send mail
?>
