How to use:

Copy Code code 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"); Theme
$mail->settext ("text Format");//Send Text format can also be a variable
$mail->sethtml ("HTML format");//Send HTML format can also be a variable
$mail->setattachments ("c:a.jpg");//Add attachments to indicate path
$mail->send (); Send mail
