PHPMailer - A full-featured email creation and transfer class for PHP。
最新版本(20181012)是PHPMailer 6.0.5，这个无法兼容php5.5以下的环境。由于我需要维护
php5.3的项目，需要切换到PHPMailer5.2来发送邮件。
下载地址： https://github.com/PHPMailer/PHPMailer/releases/tag/v5.2.24
基本使用下载解压后。新建一个测试demo。
<?php require 'PHPMailerAutoload.php'; $mail = new PHPMailer; $mail->SMTPDebug = 3; // Enable verbose debug output $mail->isSMTP(); // Set mailer to use SMTP $mail->Host = 'smtp.exmail.qq.com'; // Specify main and backup SMTP servers $mail->SMTPAuth = true; // Enable SMTP authentication $mail->Username = 'xxx@qq.com'; // SMTP username $mail->Password = 'yourpassword'; // SMTP password $mail->SMTPSecure = 'ssl'; // Enable TLS encryption, `ssl` also accepted $mail->Port = 465; // TCP port to connect to $mail->setFrom('fromWho@qq.com', 'Mailer'); $mail->addAddress('toWhom@qq.com', 'Ryan Miao'); // Add a recipient $mail->addAddress('ellen@example.com'); // Name is optional // $mail->addReplyTo('info@example.com', 'Information'); $mail->addCC('cc@example.com'); $mail->addBCC('bcc@example.com'); $mail->addAttachment('/var/tmp/file.tar.gz'); // Add attachments $mail->addAttachment('/tmp/image.jpg', 'new.jpg'); // Optional name $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>'; $mail->AltBody = 'This is the body in plain text for non-HTML mail clients'; if(!$mail->send()) { echo 'Message could not be sent.'; echo 'Mailer Error: ' . $mail->ErrorInfo; } else { echo 'Message has been sent'; }开启SMTPDebug可以查看日志
`0` No output `1` Commands `2` Data and commands `3` As 2 plus connection status `4` Low-level data output错误信息保存在 $mail->ErrorInfo对象中。
保存为mail.php, 命令行执行
php mail.php即可看到日志，以及邮件发送成功。
