php7.3-一个支持附件及html代码的邮件发送类

在平时的PHP项目中,经常需要用到邮件(Email)发送的功能,今天分享一个自己用了多年的支持附件、支持html代码的邮件发送类,代码只有600行,该有的功能全有,支持最新的php7.3.1,有详细的调用例子,大家在使用过程中,调试和报错这二个函数是方便调试时用的,在使用过程中直接把这二行代码隐藏掉就可以了,话不多了,下面直接上代码。

if($return[0]==true){
echo $return[1]."恭喜,邮件发送成功!";
}else{
	echo $return[2]."错误,邮件发送失败!";}

	$mail = new MySendMail();
	$mail->setServer("smtp.qq.com", "QQ帐号", "邮箱pop/stmp授权码", 25, false); //端口由25改成465,false改成true 变是SSL链接,
	$mail->setCtype("text/html");//html:text/html,纯文本:text/plain
