[Using githup to make php code opensource, keeping details of server secure]

Hi Little Help Needed
I have created a new website
In the index.php file i want to show records from database

Now, here is how the problem arise
I want to import codes from github intead of hosting those files on my server because i want to keep it opensource

Below is the code I am using
<?php
// connect to the database
include('connect-db.php');

// get results from database
$sql = "SELECT id, upadhi, name FROM munishri";
$result = $conn->query($sql);

if ($result->num_rows > 0) {
// output data of each row
while($row = $result->fetch_assoc()) {
echo "id: " . $row["id"]. " - Name: " . $row["upadhi"]. " " . $row["name"]. "<br>";
}
} else {
echo "0 results";
}

// close connection
$conn->close();
?>

Can i host the code to show result in another file and use something like
<?php
// connect to the database
include('connect-db.php');

// get results from database
include('http://rawgit.com/thehitechpanky/jainmunilocator/master/database.php');
?>
