do {
    $dear = "<font face='Arial' size='2'>Dear " . $row["forename"] . ",<br><br></font>";

    $email_body = $dear . "<font face='Arial' size='2'>" . stripslashes($body) . "</font><br><br><font face='Arial' size='2'>" . $linky . "  <a href='" . $row["link"] . "'> " . $row["link"] . "</a> </font> <br><br><font face='Arial' size='2'>" . stripslashes($body2) . "</font>";

    $subject = $sub;

$bcc = "blob.blob@blob.co.uk";
$recipients = $row["email"].",".$bcc;
// Constructing the email
$sender = $bcc;                                             
$recipient = $recipients;                               
$subject = $subject;                                                

$html = $email_body;      
$crlf = "\n";
    $headers = array(
        'To'        => $row["Mail"],
        'From'          => $sender,
        'Return-Path'   => $sender,
        'Subject'       => $subject
                     );

// Creating the Mime message
$mime = new Mail_mime($crlf);

// Setting the body of the email
//$mime->setTXTBody($text);
    $mime->setHTMLBody($html);


// Set body and headers ready for base mail class
$body = $mime->get();
$headers = $mime->headers($headers);

// SMTP authentication params
$smtp_params["host"]     = "scr.emserv.com";
$smtp_params["port"]     = "25";
$smtp_params["auth"]     = true;
$smtp_params["username"] = "blob.blob@blob.co.uk";
$smtp_params["password"] = "blob";

// Sending the email using smtp
$mail =& Mail::factory("smtp", $smtp_params);
sleep(2);
$result = $mail->send($recipient, $headers, $body);

for($i=0;$i<$elements1;$i++){
$bar1->increase(); //calls the bar with every processed element
$bar1->setMessage('Sending emails (2 second delay between each): '.(($i+1)*$sent).'%');

}

if($row["sent"]=='YES'){
$reminder = $row["reminder"] + 1;
$update = mysql_query("UPDATE $table SET reminder = $reminder WHERE respondent_id = " . $row["respondent_id"] . " ") or die("Could not update record<br>".mysql_error());
}else

$update = mysql_query("UPDATE $table SET sent = 'YES' WHERE respondent_id = " . $row["respondent_id"] . " ") or die("Could not update record<br>".mysql_error());

} while ($row = mysql_fetch_assoc($results));
    $bar1->setMessage('Emails have now been sent: 100%');
    }

【问题讨论】：

通过转储您传递给$mail->send() 调用的内容来进行调试 - 如果那里有双倍的电子邮件，那么是您的代码导致了问题。最后，如果邮件没有发送，您仍然更新数据库说它已发送！？

标签： php email loops pear do-while

【解决方案1】：

您看到此问题的原因是您没有清除 $body 变量。每次通过循环时，它基本上都将其附加到这一行中的 $email_body 变量中：

$email_body = $dear . "<font face='Arial' size='2'>" . stripslashes($body) ...

你将 $body 设置为整个消息：

$body = $mime->get();

get() returns the entire message as a string。最初使用 $body 也是没有意义的，因为直到我列出的第一行之后，它才在这个 do while 循环中初始化。
