adding multiple rows in mysql table based on an array - php

Question

I have a form which allows people to message each other, a user can select multiple people to message, when i submit a form it gives me the name and id of people selected to message in an array. uptil here i am able to get it to work for a single recipient
I want to be able to use this array and INSERT message for each user in different rows of mysql table
this is the array that i get when i submit a form
Array (
[to_user_id] => Array
(
[0] => 54
[1] => 55
)
[subject] => aaa
[message] => bbb
[send_message] =>
this is the part of code that works for a single recipient but not multiple
$to_user_id_array = ($_POST['to_user_id']);
$params = array(
':to_user_id' => $to_user_id_array,
':subject' => $_POST['subject'],
':message' => $_POST['message'],
':sender_id' => $this->user_id,
':status' => "0",
':type' => "message",
':sender_name' => $sender_name,
':to_user_name' => $to_user_name,
':delete_received' => 'no',
':delete_sent' => 'no',
);
$sql = "INSERT INTO `messages` (`sender_id`,`subject`,`comment`,`to_user_id`,`status`,`type`,`sender_name`,`to_user_name`,`delete_received`,`delete_sent`)
VALUES (:sender_id, :subject, :message, :to_user_id, :status, :type, :sender_name,:to_user_name,:delete_received,:delete_sent);";
parent::query($sql, $params);
$this->error = "<div class='alert alert-success'>" . _('Your message has been sent.') . "</div>";
Will really appreciate any help..

This is what worked for me, i hope this helps someone else in similar position
while ($value = $stmt->fetch(PDO::FETCH_ASSOC)) {
$params = array(
':to_user_id' => $value['user_id'],
':subject' => $_POST['subject'],
':message' => $_POST['message'],
':sender_id' => $this->user_id,
':status' => "0",
':type' => "message",
':sender_name' => $sender_name,
':to_user_name' => $value['name'],
':delete_received' => 'no',
':delete_sent' => 'no',
);
$sql = "INSERT INTO `messages` (`sender_id`,`subject`,`comment`,`to_user_id`,`status`,`type`,`sender_name`,`to_user_name`,`delete_received`,`delete_sent`)
VALUES (:sender_id, :subject, :message, :to_user_id, :status, :type, :sender_name,:to_user_name,:delete_received,:delete_sent);";
parent::query($sql, $params);
}
