Question

我正在使用以下代码（此处稍作修改以删除安全项）在表单处理后发送电子邮件并将数据插入数据库。它工作得很好，但我真正努力的一件事就是最后一个循环。在表单上，一个人可以选择他们正在输入的多个类，我需要将其添加到电子邮件中。 $ message变量的其余部分已设置。工作正常，我只是不是100％如何循环通过每个$ class []并将其添加到$ message的尾部。

非常感谢任何帮助。

$message =  "Name : " . $fname . " " . $lname . "\n<br />
                Race Date : " . date_format($datemail, 'l F jS') . "\n<br />
                Classes : ";
        for ( $i=0;$i<count($_POST['class']);$i++) {
            $class = $_POST['class'][$i];
            $message .= ", " . $class;  <<<< adds the current $class in loop at the end of $message
            // ...
        }

将for循环中的项添加到变量中
