How to send email with PHP

As an entry-level PHP developer, I often have this request: I need to add a method to automatically send emails using my own domain name as the sender's email address in my website. Use For example, sending verification code, notification information, etc. to user. The following is an introduction to using PHPMailer in PHP with QQ mailbox to realize sending emails

##Introduction to PHPMailer:

Advantages:

Can run on any platform

Supports SMTP authentication

Specify multiple recipients when sending emails, Cc address, Bcc address and reply address; Note: Adding Cc and Bcc is only supported by SMTP mode under win platform

Supports multiple email encodings including: 8bit, base64, binary and quoted-printable

Supports redundant SMTP servers, that is, you can specify the main SMTP server address or only the backup SMTP server

Supports emails with attachments, and you can add attachments in any format to emails—of course it depends on your server There is enough bandwidth to support

Customized email header information, which is similar to sending header information through the header function in PHP

Supports making the email body into HTMl content, then you can insert images into the email body

Flexible debug support

Tested and compatible SMTP servers include: Sendmail, qmail, Postfix, Imail, Exchange, etc.

Get PHPMailer:

PHPMailer project address: https://github.com/PHPMailer/PHPMailer Use the git command to clone it locally, or click "Download ZIP" directly at the bottom right of the project page to get the complete PHPMailer code package. Just decompress it locally.

Step 1: Enable our QQ mailbox to send emails

How do we say that we can send emails here? In fact, all our mailboxes can send emails, but to send emails on our website, we need to set up our QQ mailbox, because at this time our website now exists as a third-party client.

1. Since we will be using an SMTP server for sending later, it is recommended to turn on the first two items! When you click to open it, it will prompt:

After you complete the above steps, you will get an authorization code. You can copy it first and we will discuss it later. Used (if you enable two items, you will get two authorization codes, use the last one! Or click Generate Authorization Code below to get a new authorization code, it must be the latest one!).

Step 2: Enable our PHP to use QQ mailboxSend mail##PHPMailer requires PHP's socket extension support, and PHPMailer links to the qq domain name The email requires SSL encryption, and PHP must be supported by openssl. You can check phpinfo. If the following two items are present, you can use it. The openssl version number and the like are not needed. PHP in many

virtual hosts

is If the openssl extension is not supported, you may be in trouble.

How to send email with PHPStep 3: Perform certain processing on PHPMailer

Since there are many files in the PHPMailer folder we downloaded that we will not use, there is no need for us to waste this memory. We can slim down this folder. Here I only save the following files: class.phpmailer.php, class.phpmaileroauth.php, class.pop3.php, class.smtp.php, PHPMailerAutoload.php.

Step 4: Write the code for sending emails

Here I directly encapsulate a public method (written in functions. php file):

/*发送邮件方法
 *@param $to:接收者 $title:标题 $content:邮件内容
 *@return bool true:发送成功 false:发送失败
 */function sendMail($to,$title,$content){    //引入PHPMailer的核心文件 使用require_once包含避免出现PHPMailer类重复定义的警告
    require_once("phpmailer/class.phpmailer.php"); 
    require_once("phpmailer/class.smtp.php");    //实例化PHPMailer核心类
    $mail = new PHPMailer();    //是否启用smtp的debug进行调试 开发环境建议开启 生产环境注释掉即可 默认关闭debug调试模式
    $mail->SMTPDebug = 1;    //使用smtp鉴权方式发送邮件
    $mail->isSMTP();    //smtp需要鉴权 这个必须是true
    $mail->SMTPAuth=true;    //链接qq域名邮箱的服务器地址
    $mail->Host = 'smtp.qq.com';    //设置使用ssl加密方式登录鉴权
    $mail->SMTPSecure = 'ssl';    //设置ssl连接smtp服务器的远程服务器端口号,以前的默认是25,但是现在新的好像已经不可用了 可选465或587
    $mail->Port = 465;    //设置smtp的helo消息头 这个可有可无 内容任意
    // $mail->Helo = 'Hello smtp.qq.com Server';

    //设置发件人的主机域 可有可无 默认为localhost 内容任意,建议使用你的域名
    $mail->Hostname = 'http://www.lsgogroup.com';    //设置发送的邮件的编码 可选GB2312 我喜欢utf-8 据说utf8在某些客户端收信下会乱码
    $mail->CharSet = 'UTF-8';    //设置发件人姓名(昵称) 任意内容,显示在收件人邮件的发件人邮箱地址前的发件人姓名
    $mail->FromName = 'PHP中文网';    //smtp登录的账号 这里填入字符串格式的qq号即可
    $mail->Username ='12345678@qq.com';    //smtp登录的密码 使用生成的授权码(就刚才叫你保存的最新的授权码)
    $mail->Password = 'sqyofzbqlfkntbncl';    //设置发件人邮箱地址 这里填入上述提到的“发件人邮箱”
    $mail->From = '12345678@qq.com';    //邮件正文是否为html编码 注意此处是一个方法 不再是属性 true或false
    $mail->isHTML(true); 

    //设置收件人邮箱地址 该方法有两个参数 第一个参数为收件人邮箱地址 第二参数为给该地址设置的昵称 不同的邮箱系统会自动进行处理变动 这里第二个参数的意义不大
    $mail->addAddress($to,'lsgo在线通知');    //添加多个收件人 则多次调用方法即可
    // $mail->addAddress('xxx@163.com','lsgo在线通知');

    //添加该邮件的主题
    $mail->Subject = $title;    //添加邮件正文 上方将isHTML设置成了true,则可以是完整的html字符串 如:使用file_get_contents函数读取本地的html文件
    $mail->Body = $content;    //为该邮件添加附件 该方法也有两个参数 第一个参数为附件存放的目录(相对目录、或绝对目录均可) 第二参数为在邮件附件中该附件的名称
    // $mail->addAttachment('./d.jpg','mm.jpg');
    //同样该方法可以多次调用 上传多个附件
    // $mail->addAttachment('./Jlib-1.1.0.js','Jlib.js');

    $status = $mail->send();    //简单的判断与提示信息
    if($status) {        return true;
    }else{        return false;
    }
}

Next, you can call the public method to test sending emails

?php
require_once("./functions.php");
$flag = sendMail('456789@qq.com','在线通知','恭喜你成功加入PHP中文网!');
if($flag){    echo "发送邮件成功!";
}else{    echo "发送邮件失败!";
}
?>

The above is how to use PHPMailer, I hope it can help everyone.
