Question

<?php include("admin/db.php"); 
$recipients = "SELECT * FROM recipients ORDER BY id DESC";
$email_list = $db->query($recipients);
foreach($email_list as $row) {
    echo $row['email'].","; 
}

$to = "?";

?>

上面我有一个以逗号分隔的电子邮件列表，我需要将其插入到 $to 变量中。我该怎么做？

Answer 1

$recipients = "SELECT * FROM recipients ORDER BY id DESC";
while ($row = mysql_fetch_array($recipients))
{
    $adresses[] = $row['email']; 
}

$to = implode(",",$adresses);

Answer 2

foreach($email_list as $row) {
    echo $row['email'].","; 


  mail($row['mail'], $subject, $body)

}
