How to use:
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") ;//The 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") ;//To add attachments, the path must be indicated
$mail->send(); //Send email
