how to email checkbox values without multiple emails?

[lovephp]

ok so m stuck here not getting what to do, the email i want to sent it as

 

example

 

Dear Management,

 

          ABCD XYZ would like to book the following rooms

 

         Room No. 101

         Room No. 102

         Room No. 103

 

From: 2016-03-16  to: 2016-03-21

 

but with my code everything is looping and sending multiple emails, now to get foreach values inside the mail body without looping and send just one email with the number of room user selects from checkbox?

 

 

$room = $_POST['room'] = <input type="checkbox" name="room[]" value="<?php echo $roomid; ?>" /> <?php echo $roomname; ?>

 

if(isset($_POST['submit'])){

$room = $_POST['room'];
$checkin = trim($_POST['checkin']);
$checkout =trim($_POST['checkout']);
$name = trim($_POST['name']);
$phone = trim($_POST['phone']);
$email = trim($_POST['email']);

foreach($room as $rooms) {    
 $rval = 'Room No.: '.$rooms.'<br/>';
}


$headers = "From: Someone <someemail@somemail.com>\r\n";
$headers .= "Reply-To :$from\r\n";
$headers .= "Return-Path: someemail@somemail.com\r\n";   
$headers .= 'MIME-Version: 1.0' . "\n";
$headers .= 'MIME-Version: 1.0' . "\n";
$headers .= 'Content-type: text/html; charset=iso-8859-1' . "\r\n";
$headers .= 'Content-type: text/html; charset=us-ascii' . "\r\n";
'X-Mailer: PHP/' . phpversion();

$message = " ";

mail($to, $subject, $message, $headers);

}
