php - 将多行发送到一封电子邮件

Question

拜托，我有一个向客户发送电子邮件的脚本。该脚本的问题是它发送多封邮件，但我想要的只是它发送一封包含多行详细信息的邮件。即所有账单详细信息都应在表格中。

下面是我的脚本

谢谢

$bill_status = "OVERDUE";
$st = $pdo->prepare("SELECT *, DATEDIFF(NOW(), due_date) AS days_diff 
FROM bills LEFT JOIN login_details ON bills.user_id = login_details.user_id
WHERE bills.bill_status = '$bill_status'");
$st->execute();
$row_sent = $st->rowCount();

$mail = new PHPMailer;

//$mail->SMTPDebug = 3;  // Enable verbose     debug output

$mail->isSMTP(); // Set mailer to use SMTP
$mail->Host = 'localhost';  // Specify main and backup SMTP servers
$mail->SMTPAuth = true;    // Enable SMTP authentication
$mail->Username = 'mails@mail.com';                 // SMTP username
$mail->Password = 'pasword';                 // SMTP password
$mail->SMTPSecure = 'ssl'; 
$mail->Port = 465;                   // TCP port to connect to
$mail->From = 'no_reply@noreply.com';
$mail->FromName = 'Coy Name';

$mail->WordWrap = 587;        // Set word wrap to 50 characters
$mail->AddEmbeddedImage("../img/logo.png", "logo");
$mail->isHTML(true);      // Set email format to HTML
$mail->Subject = 'Notice';
while($rows = $st->fetch(PDO::FETCH_ASSOC)){
$username = $rows['username'];

$message= "
<div class='messages'>
<h3><img src='cid:my_logo'> </h3>

            <td>Bill Status</td>
            <td>Recurring</td>

$message .= "        <tr>";
$message .= "            <td>".$rows['trans_ref']."</td>";
$message .= "            <td>".$rows['due_date']."</td>";

$message .= "            <td>".$rows['recurring']."</td>";
$message .= "        </tr>";

$mail->addAddress($username);     // Add a recipient
$mail->Body    = $message;
$mail->send();
$mail->ClearAddresses();

while 循环只能围绕

$message .= "        <tr>";
....
$message .= "        </tr>";

声明。否则所有其他语句也会执行多次。
