Converting retrieved datetime from database

I'm trying to send the date to my Android device in JSON format. Also, the time is in 24 hours format. How can I change this into 12 hours format?

PHP

<?php
$sql = "SELECT * from news Order by n_date Desc";
$con = mysqli_connect($server_name, $mysql_user, $mysql_pass, $db_name);

$result = mysqli_query($con, $sql);
$response = array();
while ($row = mysqli_fetch_array($result)) {
    array_push($response, array("title" => $row[2], "content" => $row[3], "n_date" => $row[4]));
}

echo json_encode(array("news_response" => $response));

mysqli_close($con);
?>

The JSON response:

{"news_response":[{"title":"news","content":"content","n_date":"2016-11-12 10:47:23"}]}

I am trying to convert the 2016-11-12 to something like November 12, 2016 10:47:23. How do I do this?

I couldn't find any example online.
