教學目的主要有兩個
– 讓用家掌握使用終端(Terminal)及Composer的流程
-了解SMTP設定
為何需要phpmailer發送電郵?
近年垃圾電郵問題越趨嚴重，相對的主要電郵服務商如Yahoo跟Google一直在提高一些返垃圾電郵(Anti-spam)的要求。這個情況下單純使用php sendmail發送電郵很容易會被錯誤辨識為垃圾郵件，又或者需要複雜的Email Header設定才能達到成功送達效果，而phpmailer就是其中一個簡單的解決方案。
- 首先登入Directadmin網上控制台，進入”系統資訊和檔案” > “終端”。
- 先進入public_html 資料夾(假設php script需要公開)，然後輸入安裝指令
composer require phpmailer/phpmailer
- 安裝完成後，可以參考以下示範
(源始碼來自 https://github.com/PHPMailer/PHPMailer ) - 特別留意源始碼的登入設定，包括
$mail->Host = ‘mail.floppy-demo.com’;
如果使用Gmail發送電郵，主機名稱應該是smtp.gmail.com
$mail->Username = ‘[email protected]’;
$mail->Password = ‘PASSWORD’;
如果使用Gmail發送電郵，電郵密碼應該是App Password，不懂如果取得可參考這個教學。
