如何使用 phpmailer 类发送邮件？

Question

我创建了一个 phpMailer 类并将其调用到我的 register.php 文件中。但是没有找到如何从课堂发送电子邮件的方法。

这是我的课：

class mailSend {

    public function sendMail($email, $message, $subject)

    {

        require_once('PHPMailer/src/Exception.php');

        require_once('PHPMailer/src/PHPMailer.php');

        require_once('PHPMailer/src/SMTP.php');

        $mail = new PHPMailer\PHPMailer\PHPMailer();

        try {

        $mail->SMTPDebug = 0;

        $mail->isSMTP();

        $mail->Host = "smtp.gmail.com";

        $mail->SMTPAuth = true;

        $mail->Username = "[e-mail]";

        $mail->Password = "password";

        $mail->Port = 587;

        $mail->setFrom('[e-mail]', 'Mailer');

        $mail->addAddress($email);

        $mail->addReplyTo("[e-mail]", "Alias");

        $mail->CharSet = "UTF-8";

        $mail->isHTML(true);

        $mail->Subject = $subject;

        $mail->Body = $message;

        $mail->send();

            $success['success'] = "Mail sent.";

        } catch (Exception $e) {

            $errors['mail'] = "Failed. Mailer error: {$mail->ErrorInfo}";

        }

    }

}

这是 usaqe：

require "modules/mailer.php";

$email_send = new mailSend();

$email_send->sendMail($email,$message,$subject);

这是我的问题部分，我正在尝试在注册时向用户发送确认链接但不知道该怎么做，我尝试了几种方法但无法使其工作：

这是我尝试发送并出现错误的方式：

注意：未定义变量：第 115 行 D:\Wamp\www\html\modules\register.php 中的消息

require "modules/mailer.php";

$email_send = new mailSend();

$email_send->sendMail($email,$message,$subject);

$subject = "Please verify email!";

$message = "Thanks for signing up!<br>

            Please click on the link below:<br><br>

            <a href=".$url.">".$url."</a>";

您需要在使用它们之前定义变量！require "modules/mailer.php";$email_send = new mailSend();$subject = "Please verify email!";$message = "Thanks for signing up!<br>&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; Please click on the link below:<br><br>&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; <a href=".$url.">".$url."</a>";$email_send->sendMail($email,$message,$subject);要让 PHPMailer 抛出异常，您需要通过传递true给构造函数来询问它：$mail = new PHPMailer\PHPMailer\PHPMailer(true);现在要从你的类中得到响应，你需要返回一些东西，所以把你的 send 函数的结尾改成这样：$result = [];$mail->send();&nbsp; &nbsp; $result['success'] = true;&nbsp; &nbsp; $result['message'] = "Mail sent.";} catch (Exception $e) {&nbsp; &nbsp; $result['success'] = false;&nbsp; &nbsp; $result['message'] = "Failed. Mailer error: {$mail->ErrorInfo}";}return $result;然后当你调用你的函数时：$result = $email_send->sendMail($email,$message,$subject);if ($result['success']) {&nbsp; &nbsp; echo $result['message'];&nbsp; &nbsp; //Do whatever else you want to do on success} else {&nbsp; &nbsp; echo $result['message'];}
