在 github 上面有一個 PHPMailer 專案,他號稱是目前世界上最潮的 PHP send mail code production,對於編碼的支援度也很好,最重要的是他支援各種驗證機制,這讓很多目前五花八門的驗證方式相容性就提高了許多

在此篇簡單紀錄如何使用 PHPMailer
Step.1 複製 PHPMailer 專案
$ git clone https://github.com/PHPMailer/PHPMailer
Step.2 建立單封郵件測試
$ cd PHPMailer $ sendmail.php <?php require 'PHPMailerAutoload.php'; $mail = new PHPMailer; // Enable verbose debug output //$mail->SMTPDebug = 3; // Set mailer to use SMTP $mail->isSMTP(); // smtp 伺服器, 支援多台smtp server備援 $mail->Host = 'smtp1.gmail.com'; // Enable SMTP authentication $mail->SMTPAuth = true; // SMTP username $mail->Username = '[email protected]'; // SMTP password , If you must use the gmail application password $mail->Password = 'secret'; // Enable TLS encryption, `ssl` also accepted $mail->SMTPSecure = 'tls'; // TCP port to connect to $mail->Port = 587; $mail->setFrom('[email protected]', 'Mailer'); // Add a recipient , name is optional $mail->addAddress('[email protected]', 'Joe User'); $mail->addAddress('[email protected]'); // Add a recipient , $mail->addReplyTo('[email protected]', 'Information'); $mail->addCC('[email protected]'); $mail->addBCC('[email protected]'); // Add attachments , optional name $mail->addAttachment('/var/tmp/file.tar.gz'); $mail->addAttachment('/tmp/image.jpg', 'new.jpg'); // Set email format to HTML $mail->isHTML(true); $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'; }
如果你使用的是 Gmail smtp,那 Password 的部分如果你使用的是 “網頁登入的密碼” 就會被 Gmail 阻擋顯示錯誤訊息『Please log in via your web browser and then try again.』,並且要求使用 application password
申請 Gmail Application Password
登入你的 Gmail 到以下找到應用程式密碼進行新增,Gmail 會提供一組密碼給你作應用程式驗證使用。
https://myaccount.google.com/u/0/security
將密碼代入 send.php 中的 $mail->Password 就可以驗證成功!
