QQ郵箱設置

?

調用代碼示例

public function get($userId){set_time_limit(100);$mail = new Email();$connect = $mail->mailConnect('imap.qq.com', '143','****9@qq.com', '授權碼');if ($connect) {$totalCount = $mail->mailTotalCount();$list = $mail->mailList();for ($i = $totalCount; $i > 0; $i--) {$mailHeader = $mail->mailHeader($i);if($mailHeader['from'] == '***@***.com'){//郵件來源if ($mailHeader['seen'] == "U") { //未讀 if($mail->getBody($i)){//郵件內容}$subject = $mailHeader['subject']; //郵件標題$status = $mail->mailRead($i);}else{$mail->mailDelete($i);//刪除已讀}}} $mail->closeMail();//關閉 }

網上有很多讀取郵件的類，很多已經無法正常使用，還有些容易出現編碼錯誤問題，這個版本是經過我測試可以正常使用的，但是其他的郵箱沒有一一驗證。
