thinkphp3.2 实现 Phpmailer 发送邮件 配置

环境配置如下：

PHp版本：5.4.27

ThinkPhp 框架 3.2

Apache 2.4.9

使用的是 Xampp 集成的环境

第一步:

我们建立一个 NewsController.class 控制器， 代码如下：

<?php// +----------------------------------------------------------------------// | Author: eiengwch// +----------------------------------------------------------------------namespace Home\Controller;use Think\Controller;/*** 前台首页控制器* 主要获取首页聚合数据*/class NewsController extends HomeController {public function mail(){$demo =$this->postmail('eiengwch@', '这是标题', '这是正文'); }/*** 配置的邮件* @param string $to 收件人地址* @param string $subject 邮件标题* @param string $body邮件正文*/function postmail($to, $subject = '',$body = ''){//$to 表示收件人地址 //$subject表示邮件标题//$body 表示邮件正文//error_reporting(E_ALL);error_reporting(E_STRICT);date_default_timezone_set('Asia/Shanghai'); //设定时区东八区import('Vendor.Mail.Phpmailer'); // 引入 Phpmailer 类文件import('Vendor.Mail.Smtp'); // 引入 Smtp 类文件$mail = new \PHPMailer(); //new一个PHPMailer对象出来// require_once THINK_PATH.'Library\Vendor\Mail\PHPMailer.class.php';// require_once THINK_PATH.'Library\Vendor\Mail\Smtp.class.php';// linux 下引入// vendor('PHPMailer.class#phpmailer');// vendor('PHPMailer.class#smtp');// $mail = new \PHPMailer(); //new一个PHPMailer对象出来$body = eregi_replace("[\]",'',$body);//对邮件内容进行必要的过滤$mail->CharSet ="UTF-8";//设定邮件编码，默认ISO-8859-1，如果发中文此项必须设置，否则乱码$mail->IsSMTP(); // 设定使用SMTP服务$mail->SMTPDebug = false; // 启用SMTP调试功能 开始为true 可以为1， 2// 1 = errors and messages// 2 = messages only$mail->SMTPAuth = true; // 启用 SMTP 验证功能$mail->SMTPSecure = "ssl"; // 安全协议，可以注释掉$mail->Host = ''; // SMTP 服务器$mail->Port = 465;// SMTP服务器的端口号$mail->Username = 'eiengwch@';// SMTP服务器用户名，就是邮箱登陆名$mail->Password = '88'; // SMTP服务器密码 登陆密码$mail->SetFrom('eiengwch@', 'who'); //设置邮件发送地址, 和SMTP服务器用户名相等$mail->AddReplyTo('xxx@xxx.xxx','bbb');//回复地址 姓名 (可填可不填)$mail->Subject = $subject;//邮件标题$mail->AltBody = '1111'; //附加信息，可以省略$mail->MsgHTML($body); //邮件内容$address = $to; //收件人地址$mail->AddAddress($address, '');//$mail->AddAttachment("img/demo.png");//添加附件//判断是否发送成功if(!$mail->Send()) {echo 'Mailer Error: ' . $mail->ErrorInfo;} else {echo "Message sent!恭喜，邮件发送成功！";}}

然后我们把下载的 Phpmailer 类文件放在 ThinkPHP\Library\Vendor\Mail 下面 ； Mail 是我新建的文件夹 如下：

然后我们访问这个控制器， 就ok了

其余配置项：Phpmailer.class.php 文件代码如下： 可以在网上下载这个包
