PHP mail sending function--Detailed introduction of ThinkPHP3.2.3 code

First step: download a PHPMailer plug-in on the Internet, plug-in address "http://www.php.cn/" After downloading and decompressing, we only need to use two of the files here, as shown in the following figure:

Place the two files class.phpmailer.php and class.smtp.php respectively to
ThinkPHP/Library/Vendor/PHPMailer/class .phpmailer.php (note case)
ThinkPHP/Library/Vendor/PHPMailer/class.smtp.php

Note: Now The default third-party class library directory of thinkPHP is placed. If it is defined in index.php such as define('VENDOR_PATH',APP_PATH.'Common/Vendor/'); then the file placement path must be the same as it to avoid class ' PHPMailer' not found situation.

2. Create a user-defined function file Application/Home/Common/function.php and place the following functions:

1 /**
 2  * 功能：邮件发送函数
 3  * @param string $to 目标邮箱
 4  * @param string $subject 邮件主题（标题）
 5  * @param string $to 邮件内容
 6  * @return bool true
 7  */
 8  function sendMail($to, $subject, $content) {
 9     vendor('PHPMailer.class#smtp'); 
10     vendor('PHPMailer.class#phpmailer');    //注意这里的大小写哦，不然会出现找不到类，PHPMailer是文件夹名字，class#phpmailer就代表class.phpmailer.php文件名
11     $mail = new PHPMailer();
12     // 装配邮件服务器
13     if (C('MAIL_SMTP')) {
14         $mail->IsSMTP();
15     }
16     $mail->Host = C('MAIL_HOST');  //这里的参数解释见下面的配置信息注释
17     $mail->SMTPAuth = C('MAIL_SMTPAUTH');  
18     $mail->Username = C('MAIL_USERNAME');
19     $mail->Password = C('MAIL_PASSWORD');
20     $mail->SMTPSecure = C('MAIL_SECURE');
21     $mail->CharSet = C('MAIL_CHARSET');
22     // 装配邮件头信息
23     $mail->From = C('MAIL_USERNAME');
24     $mail->AddAddress($to);
25     $mail->FromName = C('MAIL_FROMNAME');
26     $mail->IsHTML(C('MAIL_ISHTML'));
27     // 装配邮件正文信息
28     $mail->Subject = $subject;
29     $mail->Body = $content;
30     // 发送邮件
31     if (!$mail->Send()) {
32         return FALSE;
33     } else {
34         return TRUE;
35     }
36  }

3. In the above function, the C method is used to load some configuration information, so we have to add the following configuration information to the configuration file (default/Application/Home/Conf/config.php) ：

<?php
 2  return array(
 3     //其他配置项省略......
 4     // 配置邮件发送服务器
 5     &#39;MAIL_SMTP&#39;            =>  TRUE,
 6     &#39;MAIL_HOST&#39;            =>  &#39;smtp.163.com&#39;,          //邮件发送SMTP服务器
 7     &#39;MAIL_SMTPAUTH&#39;   =>  TRUE,
 8     &#39;MAIL_USERNAME&#39;   =>  &#39;123***@163.com&#39;,       //SMTP服务器登陆用户名
 9     &#39;MAIL_PASSWORD&#39;   =>  &#39;123456abc&#39;,              //SMTP服务器登陆密码
10     &#39;MAIL_SECURE&#39;         =>  &#39;tls&#39;,
11     &#39;MAIL_CHARSET&#39;       =>  &#39;utf-8&#39;,
12     &#39;MAIL_ISHTML&#39;         =>  TRUE,
13     &#39;MAIL_FROMNAME&#39; =>  &#39;某某网站客户&#39;,
14  );

4. Start calling, assuming it is accessed through the URL /?m=home&c=index&a=send, then we add the corresponding method to the Application/Home/Controller/IndexController.class.php file, as follows:

1 <?php
 2  namespace Home\Controller;
 3  use Think\Controller;
 4  class IndexController extends Controller {
 5     public function index(){
 6         
 7     }
 8     public function send(){
 9         if(sendMail(&#39;vsiryxm@qq.com&#39;,&#39;你好!邮件标题&#39;,&#39;这是一篇测试邮件正文！&#39;)){
10             echo &#39;发送成功！&#39;;
11         }
12         else{
13             echo &#39;发送失败！&#39;;
14         }
15     }
16  }
