我試圖使用的PHPMailer發送多封電子郵件（不同的電子郵件給每個收件人）

Question

第一次發佈這樣不勝感激任何幫助......

• 我很高興的SQL查詢工作，並返回兩張2行
• 我很高興離開消息「你好」現在
• 我已經通過很多答案看上去和沒有解決我的問題
• 該功能可以將郵件發送到只（前2 ）收件人，但不是第二個。

如果有人能告訴我在哪裏，我錯了，我會非常感激......

Answer 1

首先，你真的應該先檢查PHPMailer的文檔，因爲有an example that does exactly this。你不可能看起來太辛苦。

在您的代碼中，請勿在每次循環時創建新的PHPMailer實例 - 在循環之前，應該將所有保持不變的東西（isSmtp，Host，Port等）設置爲一次。在循環中，你應該做這些事情：

• 設置郵件正文
• 將收件人
• 發送郵件
• 商店的任何錯誤
• 清除收件人列表（使用clearAllRecipients()）

您的發送檢查後還得到return聲明 - 這些聲明將完全退出您的功能，因此它會失效我永遠不會發送多條消息。你應該在你瀏覽清單時收集錯誤，並在最後呈現（或返回）它們。

Answer 2

我使用了上面@synchro建議的while循環，就在addAddress的周圍。 Foreach迭代器語法無法正常工作，因爲我使用的是PHP 5.3（如上面鏈接到PHPmailer的註釋）。

然後我在while循環之外取回了返回值，一切正常。

這是工作的代碼： （它的任何改進欣然接受）
