PHP send email class

PHP’s send email class is very powerful. It can not only send emails in html format, but also send attachments
class Email {

var $mailBCC = ""; // Secret CC
var $mailFrom = ""; // Sender
var $mailSubject = ""; // Subject
var $mailText = ""; // The body of the letter in text format
var $mailHTML = ""; // Email body in html format
var $mailAttachments = ""; // Attachments

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
