Question

我对如何使用foreach感到有点困惑。我在上面读了一些互联网的东西，我有点理解它是如何工作的，但我并不完全理解它。我想我可以使用foreach创建一个PHP大规模电子邮件程序，它将空白的抄送发送到电子邮件地址，并通过主题中的名称来对待客户（亲爱的，迈克尔这是您的电子邮件）。我已经想出如何从我的数据库中检索名称和电子邮件到变量，我知道如何发送电子邮件，但我不知道如何一次发送多封电子邮件并关联名称和电子邮件地址。

<?php
        //Variables for connecting to your database.
        //These variable values come from your hosting account.
        $hostname = "MichaelBerna.db.10339998.hostedresource.com";
        $username = "MichaelBerna";
        $dbname = "MichaelBerna";

     //These variable values need to be changed by you before deploying
        $password = "********";
        $usertable = "subscribers";
        $yourfield = "name";
        $yourfield1 = "email";

        //Connecting to your database
        $link = mysql_connect($hostname, $username, $password) OR DIE ("Unable to connect to database! Please try again later.");
        mysql_select_db($dbname);

        //Fetching from your database table.
        $query = "SELECT * FROM $usertable";
        $result = mysql_query($query);

        if ($result) 
        {
            while($row = mysql_fetch_array($result)) 
            {                    
                $name = $row["$yourfield"];
                $email = $row["$yourfield1"];
                echo "Name: $name<br>";
                echo "Email: $email<br>";
                //mysqli_free_result($result);
                //mysqli_close($link);
            }
        }

        ?>

这是我的电子邮件代码：

        <?php

    require_once '../PHPMailer_5.2.2/class.phpmailer.php';

    $name = $_POST['name'] ;

    $email = $_POST['email'] ;

    //$file = $_POST['file'] ; // I'm going to later add a file later to be attached in email from database


    $body = "Hey $name thank you for continuing to be a valued customer! This month's story is included in this email asa an attachment.";

    $mail = new PHPMailer(true); //defaults to using php "mail()"; the true param means it will throw exceptions on errors, which we need to catch


    try 

    {

      $mail->AddAddress($email, $name);

      $mail->SetFrom('admins_email@yahoo.com', 'Site Admin');

      $mail->AddReplyTo('admins_email@yahoo.com', 'Site Admin');

      $mail->Subject = "Dear $name Your monthly subscription has arrived!";

      $mail->Body = $body;

      if ($_FILES['file']['size']) 

      {

      $mail->AddAttachment($_FILES['file']['tmp_name'], $_FILES['file']['name']);// attachment

      }

      $mail->Send();

      echo "Email Sent Successfully</p>\n";   

    } 

    catch (phpmailerException $e) 
    {

      echo $e->errorMessage(); //Pretty error messages from PHPMailer

    } 
    catch (Exception $e) 
    {

      echo $e->getMessage(); //Boring error messages from anything else!

    }

?>

基本上，我需要一种方法来组合这两个脚本并将它们链接在一起，这就是我不确定如何做的事情。

将邮寄代码放在一个函数中，例如send_mail()，以便可以从不同的地方调用它。然后将数据库查询循环更改为：

while ($row = mysql_fetch_assoc($result)) {
    send_mail($row['name'], $row['email'), "Text of the email");
}

PHP Foreach用于从数据库发送电子邮件？
