我的sendemail函數多次使用返回redeclare或undefine var錯誤

Question

我很難搞清楚如何在我的expired_account（）函數中多次使用我的sendemail（）函數，具體取決於它發現的內容。首先它會檢查8天內到期的帳戶，發送電子郵件，然後檢查1天，發送電子郵件，然後檢查過期帳戶 - 發送電子郵件。

8天的第一次檢查工程..電子郵件與沒有錯誤發送，但任何其他sendemail（）返回一個錯誤，或者是

include_once：

Notice: Undefined variable: mail in C:\www\dev\common.inc on line 4585 Fatal error: Call to a member function setFrom() on a non-object in C:\www\dev\common.inc on line 4585 

或當我改變include_once只是包括：

Fatal error: Cannot redeclare PHPMailerAutoload() (previously declared in C:\www\dev\phpmailer\PHPMailerAutoload.php:24) in C:\www\dev\phpmailer\PHPMailerAutoload.php on line 31 

我sendemail功能：

function sendemail($wordwrap=50, $html=true, $to, $cc='', $cc2='', $cc3='', $subject, $body) { 

include_once "phpmailer/phpmailer.inc"; 

global $systememail; 
$fromname = "System Mail"; 

$mail->setFrom($systememail, $fromname); 
$mail->addAddress($to); 
if ($cc != "") 
$mail->addCC($cc); //CC 
if ($cc2 != "") 
$mail->addCC($cc2); //CC 
if ($cc3 != "") 
$mail->addCC($cc3); //CC 
$mail->WordWrap = $wordwrap; // Set word wrap to 50 characters 
$mail->isHTML($html);   // Set email format to HTML 
$mail->Subject = $subject; 
$mail->Body = $body; 

    if(!$mail->send()) { 
     $maxTries = 3; 
     for ($try=1; $try<=$maxTries; $try++) { 
      usleep(5000); 
      if ($mail->send()) { 
      break; 
      } 
      if ($try >= 3) { 
      exit; 
      } 
     } 
    } 
} 

我的代碼執行sendemail（）函數：

if ($daysleft == 8) { 
      //do this for 8 days left before contract ends 
      $subject = "Contract for $fullname expires in $daysleft days"; 
      $body = " Account expiring in $daysleft days"; 
    sendemail($wordwrap=50, $html=true, $email, $manageremail, '', '', $subject, $body); 
    } 

    if ($daysleft == 1) { 
      //do this for 1 day left before contract ends 
      $subject = "Contract for $fullname expires in $daysleft days *FINAL NOTICE*"; 
      $body = "Account expiring in $daysleft days"; 
    sendemail($wordwrap=50, $html=true, $email, $manageremail, '', '', $subject, $body); 
    } 

    if ($todaydate >= $contractend_TS) { 
      //do this for expired accounts.... : 
      $subject = "Contract for $fullname has expired"; 
      $body = "Contract for $fullname has expired"; 
    sendemail($wordwrap=50, $html=true, $email, $manageremail, '', '', $subject, $body); 
    }

看樣子$mail變量被設置/初始化時，您包括您phpmailer/phpmailer.inc文件。

當您使用include_once時，它只會在第一次調用您的函數時包含，因此只有第一次設置$mail變量和所需的對象。

您應該將該文件包含在該函數之外，並將$mail變量作爲參數發送給該函數。

你將不得不檢查，如果你需要使用它第二次之前重置您$mail變量，這將取決於你所使用的郵件。
