PHPMailer 是一套功能強大的的Mail套件
詳細資料可查看PHPMailer GitHub: https://github.com/PHPMailer/PHPMailer
下載整包程式碼wget https://github.com/PHPMailer/PHPMailer/archive/master.zip
解壓縮unzip master.zip
而直接複製GitHub的Sample Code最常見的錯誤就是找不到 autoload.php
Warning: require(vendor/autoload.php): failed to open stream: No such file or directory Fatal error: require(): Failed opening required 'vendor/autoload.php' (include_path='.:/usr/share/php')
因為GitHub裡的Sample code是走Composer路線的,Composer是PHP管理套件的工具
而 autoload.php 要跑過 Composer 才會出現
Composer & autoload.php 的關係,後續有機會再另開文章解說
會出錯多半是沒 Composer 直接拿 Composer 的語法下去用,所以 GitHub官網有這段說明
Alternatively, if you're not using Composer, copy the contents of the PHPMailer folder into one of theinclude_path
directories specified in your PHP configuration and load each class file manually:<?php use PHPMailer\PHPMailer\PHPMailer; use PHPMailer\PHPMailer\Exception; require 'path/to/PHPMailer/src/Exception.php'; require 'path/to/PHPMailer/src/PHPMailer.php'; require 'path/to/PHPMailer/src/SMTP.php';
If you're not using theSMTP
class explicitly (you're probably not), you don't need ause
line for the SMTP class.
所以這邊修改一下不用 Composer 做法就可以直上了
如果不是用Google的SMTP,也可以視情況修改參數
<?php
//移除Composer語法
// 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\SMTP;
//use PHPMailer\PHPMailer\Exception;
// Load Composer's autoloader
//require 'vendor/autoload.php';
//新增
use PHPMailer\PHPMailer\PHPMailer;
use PHPMailer\PHPMailer\Exception;
//設定檔案路徑
require 'path/to/PHPMailer/src/Exception.php';
require 'path/to/PHPMailer/src/PHPMailer.php';
require 'path/to/PHPMailer/src/SMTP.php';
//建立物件
$mail = new PHPMailer(true);
try {
//Server settings
//$mail->SMTPDebug = SMTP::DEBUG_SERVER; // Enable verbose debug output
$mail->SMTPDebug = 0; // DEBUG訊息
$mail->isSMTP(); // 使用SMTP
$mail->Host = 'smtp.gmail.com'; // SMTP server 位址
$mail->SMTPAuth = true; // 開啟SMTP驗證
$mail->Username = 'Gmail帳號'; // SMTP 帳號
$mail->Password = 'Gmail密碼(*註1)'; // SMTP 密碼
//$mail->SMTPSecure = PHPMailer::ENCRYPTION_STARTTLS; // Enable TLS encryption; `PHPMailer::ENCRYPTION_SMTPS` also accepted
$mail->SMTPSecure = "ssl"; // Gmail要透過SSL連線
$mail->Port = 465; // SMTP TCP port
//設定收件人資料
$mail->setFrom('from@example.com', 'Mailer'); // 寄件人(透過Gmail發送會顯示Gmail帳號為寄件者)
$mail->addAddress('apple@example.com', 'Apple User'); // 收件人會顯示 Apple User<apple@example.com>(*註2)
// $mail->addAddress('banana@example.com'); // 名字非必填
$mail->addReplyTo('info@example.com', 'Information'); //回信的收件人
$mail->addCC('cc@example.com'); //副本
$mail->addBCC('bcc@example.com'); //密件副本
// 附件
$mail->addAttachment('/var/tmp/file.tar.gz'); // 附件 (*註3)
// $mail->addAttachment('/tmp/image.jpg', 'new.jpg'); // 插入附件可更改檔名
// 信件內容
$mail->isHTML(true); // 設定為HTML格式
$mail->Subject = 'Here is the subject'; // 信件標題
$mail->Body = 'This is the HTML message body <B>in bold!</B>'; // 信件內容
$mail->AltBody = 'This is the body in plain text for non-HTML mail clients'; // 對方若不支援HTML的信件內容
$mail->send();
echo 'Message has been sent';
} catch (Exception $e) {
echo "Message could not be sent. Mailer Error: {$mail->ErrorInfo}";
}
?>
*註1 若要讓透過Gmail發信,Gmail帳號也需要設定 如果未開啟兩步驟驗證,需要開啟低安全性應用程式存取權: https://support.google.com/accounts/answer/6010255?hl=zh-Hant 若已經開啟兩步驟驗證,則要設定應用程式密碼(建議): https://support.google.com/accounts/answer/185833?hl=zh-Hant 如果有使用G Suite,還可以使用relay(有限發送數量) https://support.google.com/a/answer/2956491?hl=zh-Hant
*註2 若要發送給多人:$mailto = array( 'user1@example.com' => 'user1', 'user2@example.com' => 'user2', 'user3@example.com' => 'user3', ); if(is_array($mailto)){ foreach ($mailto as $email => $name) { $mail->AddAddress("$email","$name"); } }else{ $mail->AddAddress("$mailto"); }
另外的做法就是直接疊上去$mail->addAddress('user1@example.com', 'user1'); $mail->addAddress('user2@example.com', 'user2'); $mail->addAddress('user3@example.com', 'user3');
*註3
附件如果要插入多個檔案:
$files = array($file1,$file2,$file3,$file4,$file5);
$mail->AddAttachment("$files");
