如何从数据库查询(PHP)向多个收件人发送电子邮件

Question

我正在尝试将电子邮件发送到我的数据库中的多个电子邮件地址.这是我目前的代码.它仅在我指定单个电子邮件地址时才起作用,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.我在哪里错了？

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到一个"收件人"字段中.其他用户可能不喜欢其他人看到这一点.也许你的smtp函数会破坏数组,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); 
            }
        }
 }
