结果只是电子邮件根本没有分开。
$query = "SELECT email FROM wp_newsman_lst_wp_users";
$result = mysql_query($query);
while($row = mysql_fetch_array($result))
{
$new_array[$row['email']]['email'] = $row['email'];
}
foreach($new_array as $array)
{
$to = $array['email'];
$mail_list = implode(", ", (array)$to);
}
echo $mail_list;
结果就是电子邮件根本没有分开。
您必须在foreach循环之外进行implode()调用，因此使用以下命令：
foreach($new_array as $array) {
$to[] = $array['email'];
//^^ So you actually have a array
}
$mail_list = implode(", ", $to);
//^^^^^^^ Outside of the foreach loop
