我正在使用下面的代码发送网络邮件和短信通知。它工作得很好，但我只想在用户从需要服务的下拉菜单中选择“A”值并且不想在晚上 8 点到早上 5 点接收短信时接收短信。
任何帮助都非常感谢..
<form action="/thankyou.php" name="form1" method="post" >
<input type="hidden" name="curtime" />
<select name="servicerequired">
<option selected="selected" value="">Please Choose</option>
<option value="A">Replacement</option>
<option value="B">Architectural</option>
<option value="C">Commercial</option>
<option value="other">Other</option>
</select>
<input type="submit" value="submit" name="submit" />
这是PHP部分
if ($_POST['submit']) {
$to="myemail@mydomain.com";
$sms="mymobilenumber@domain.net";
$subject="Online Quote";
$from = "webmaster@mydomain.com";
$curtime = $_REQUEST['curtime'] ;
$service = $_REQUEST['servicerequired'] ;
$curtime = date("Y-m-d H:i:s");
$headers = "From: $from\r\n" .
"MIME-Version: 1.0\r\n" .
"Content-Type: multipart/mixed;\r\n" .
" boundary=\"{$mime_boundary}\"";
$message="message to email";
$message2="message to sms";
@mail($to, $subject, $message, $headers);
@mail($sms, $subject, $message2, $headers);
