phpmailer

一、下载 安装 phpmailer

"phpmailer/phpmailer": "~6.0"

or run

composer require phpmailer/phpmailer

二、查看是否开启 socket 和 openssl 扩展

三、示例

<?php
// Import PHPMailer classes into the global namespace
// These must be at the top of your script, not inside a function
use PHPMailer\PHPMailer\PHPMailer;
use PHPMailer\PHPMailer\Exception;

// Load Composer's autoloader
require 'vendor/autoload.php';

// Instantiation and passing `true` enables exceptions
$mail = new PHPMailer(true);

try {
//Server settings
$mail->SMTPDebug = 2; // Enable verbose debug output
$mail->isSMTP(); // Set mailer to use SMTP
$mail->Host = 'smtp.qq.com'; // Specify main and backup SMTP servers
$mail->SMTPAuth = true; // Enable SMTP authentication
$mail->Username = '2355430977@qq.com'; // SMTP username
$mail->Password = 'wftypuzfvplwdicf'; // SMTP password
$mail->SMTPSecure = 'ssl'; // Enable TLS encryption, `ssl` also accepted
$mail->Port = 465; // TCP port to connect to

//Recipients
$mail->setFrom('2355430977@qq.com', '万圣伟业');
$mail->addAddress('66500852@qq.com', 'Joe User'); // Add a recipient
// $mail->addAddress('ellen@example.com'); // Name is optional
$mail->addReplyTo('asdasdcn@qq.com', 'Information');
$mail->addCC('asdasdcn@qq.com');
// $mail->addBCC('bcc@example.com');

// // Attachments
// $mail->addAttachment('/var/tmp/file.tar.gz'); // Add attachments
// $mail->addAttachment('/tmp/image.jpg', 'new.jpg'); // Optional name

// Content
$mail->isHTML(true); // Set email format to HTML
$mail->Subject = 'Here is the subject';
$mail->Body = 'This is the HTML message body <b>in bold!</b>';
$mail->AltBody = 'This is the body in plain text for non-HTML mail clients';

$mail->send();
echo 'Message has been sent';
} catch (Exception $e) {
echo "Message could not be sent. Mailer Error: {$mail->ErrorInfo}";
}
