# php实现发送邮件，ssl版，QQ邮箱可用，有些同学的实现不了是因为端口用的默认的25，阿里云服务器屏蔽了25端口，现在我们用465端口，亲测可用，已经解决各种问题 #

### 现在我们先贴上邮箱发送的类代码 ###

### 下面贴出咱的引用发送邮箱类代码 ###

            $mail->setServer("smtp.qq.com", "123456@qq.com", "mima",465,true); //参数1（qq邮箱使用smtp.qq.com，qq企业邮箱使用smtp.exmail.qq.com），参数2（邮箱登陆账号），参数3（邮箱登陆密码，也有可能是独立密码，就是开启pop3/smtp时的授权码），参数4（默认25，腾云服务器屏蔽25端口，所以用的465），参数5（是否开启ssl，用465就得开启）//$mail->setServer("XXXXX", "joffe@XXXXX", "XXXXX", 465, true);
            $mail->setFrom("123456@qq.com"); //发送者邮箱
            $mail->setReceiver("123456789@qq.com"); //接收者邮箱
            $mail->addAttachment(""); //Attachment 附件，不用可注释
            $mail->setMail("测试一下", "<b>测试</b>"); //标题和内容
            $mail->send();//可以var_dump一下，发送成功会返回true，失败false
        }

小结：  
使用QQ邮箱的话，需要开启POP3和SMTP服务。开启方式如下  
QQ邮箱 > 设置 > 账户>开启服务：POP3和SMTP服务

需要 PHP 的 sockets 扩展支持，而登录 QQ 邮箱 SMTP 服务器则必须通过 SSL 加密，故 PHP 还得包含 openssl 的支持。
