Recommend a fully functional PHP email class_PHP tutorial

PHP--The function of the following class is very powerful. It can not only send emails in html format, but also send attachments
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 email
?>

Copy code The code is as follows:

class Email {
//---Set global variables
var $mailTo = ""; // Recipients
var $mailCC = ""; / / Cc
var $mailBCC = ""; // Secret Cc
var $mailFrom = ""; // Sender
var $mailSubject = ""; // Subject
var $mailText = ""; // The body of the letter in text format
var $mailHTML = ""; // The body of the letter in html format
var $mailAttachments = ""; // Attachments
