How to use PHP to implement email sending function? The following article will introduce to you how to send emails using PHP using phpmailer and SMTP services. I hope it will be helpful to you!

Occasionally there will be messages and comments on the blog, and I will reply in time. But there is a question. After I replied, if the person who left me a message does not enter my blog again Check, he doesn't know, this is very unreasonable.

Check out other people’s blogs. Most replies are via email.

This is pretty good, let’s get one.

Basically two methods are introduced on Baidu.

The first is that PHP implements email sending through the SMTP server of qq mailbox or NetEase mailbox.

The second is to use phpmailer to send emails.

Note that the second method also requires your email to enable the SMTP service.

The final effect of how to open the SMTP service of the mailbox is as shown below:

During the opening process, the page will prompt you to call The SMTP authorization password is as shown in the figure below. This password must be remembered. If you do not remember it, you can generate it again. I have opened two SMTP services above, and the final authorization password shall prevail.

The first method has been tried, and the error is as follows:

Trying to smtp.qq.com:587 220 smtp.qq.com Esmtp QQ Mail Server Connected to relay host smtp.qq.com > 
HELO localhost 250 smtp.qq.com > AUTH LOGIN ODA1Nzk1OTU1QHFxLmNvbQ== 530 Must issue a STARTTLS command first. 
Error: Remote host returned "530 Must issue a STARTTLS command first." 
Error: Error occurred while sending HELO command. 
Error: Cannot send email to <1150366147@qq.com> Disconnected from remote host

I searched on Baidu and found no clear answer. If you have encountered such a problem, please leave a message below and we can discuss it.

I am using the second method here.

I won’t go into details about the specific advantages and disadvantages of Phpmail. If you want to know more, please go to Baidu.

The first step is to get phpmailer

PHPMailer project address: https://github.com/PHPMailer/PHPMailer; use git command to clone to Locally, or directly click "Download ZIP" in the lower right corner of the project page to get the complete PHPMailer code package, and then unzip it locally.

The second step is to enable server support

To use phpmailer, our server needs to enable sockets and openssl services.

#The third step is to upload phpmailer to our server.

I am using the thinkphp5 framework here, and I uploaded it to the extend directory in the root directory.

There is actually no need to mention this step in isolation. However, not all of the project files we downloaded from github are useful. We can only upload a few main files to the server.

The fourth step is to encode the public method of sending mail and its calling method

The public method of sending mail:

/*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 = 'https://guanchao.site';
 
    //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 = 'LSGO实验室';
 
    //smtp登录的账号 这里填入字符串格式的qq号即可
    $mail->Username ='805795955@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 = '****************';
 
    //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 = '805795955@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,'时间里的博客在线通知');
 
    //添加多个收件人 则多次调用方法即可
    // $mail->addAddress('**********@qq.com','时间里的博客在线通知');
 
    //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;
    }
}

Calling method :

I am just making a simple call here. Please decide what content you need based on your own needs.

public function sendEmail()
{
       $flag = sendMail('805795955@qq.com','时间里的博客在线通知','欢迎来到时间里的博客');
       if($flag){
              echo true;
       }else{
              echo false;
       }
}

The above is the entire implementation process of sending emails using phpmailer.
