php - 如何从数据库查询(PHP)向多个收件人发送电子邮件

Question

我正在尝试向数据库中的多个电子邮件地址发送电子邮件。这是我当前的代码。它仅在我指定单个电子邮件地址时有效，但是，我需要让他们查询我的数据库并将电子邮件发送到每个电子邮件地址。我哪里出错了？

function sendmail($cat, $user) {
    require_once "Mail.php";
    $elist = mysql_query("SELECT cEmail FROM tblUsers WHERE cAlerts = 'All' AND cEAlerts = 'Yes' AND cPreferences LIKE '%$cat%';");
    $elist = mysql_fetch_array($elist);

    $from = "EMAIL ADDRESS";
    $to = $elist;
    $subject = "SUBJECT";
    $body = "BODY";

    $host = "smtp.domain.com";
    $username = "USERNAME";
    $password = "PASSWORD";

    $headers = array ('From' => $from,
    'To' => $to,
    'Subject' => $subject);
    $smtp = Mail::factory('smtp',
    array ('host' => $host,
    'auth' => true,
    'username' => $username,
    'password' => $password));

    $mail = $smtp->send($to, $headers, $body);
 }

尝试这样的事情，但需要注意的一点是，您应该单独发送电子邮件，而不是将所有电子邮件地址分组在一个“收件人”字段中。其他用户可能不喜欢其他人看到它。也许您的 smtp 函数分解了数组，不确定 :-|

function sendmail($cat, $user)
{ 
    require_once "Mail.php"; 
    $elist = mysql_query("SELECT cEmail FROM tblUsers WHERE cAlerts = 'All' AND cEAlerts = 'Yes' AND cPreferences LIKE '%$cat%';"); 

    $from = "EMAIL ADDRESS"; 
    $subject = "SUBJECT"; 
    $body = "BODY"; 

    $host = "smtp.domain.com"; 
    $username = "USERNAME"; 
    $password = "PASSWORD"; 

        if(mysql_num_rows($elist) > 0)
        {
            while($elist_result = mysql_fetch_array($elist))
            {
            $headers = array ('From' => $from, 
            'To' => $elist_result['cEmail'], 
            'Subject' => $subject); 
            $smtp = Mail::factory('smtp', 
            array ('host' => $host, 
            'auth' => true, 
            'username' => $username, 
            'password' => $password)); 

            $mail = $smtp->send($to, $headers, $body); 
            }
        }
 }
