Create server file to fetch data from database and return in json format.

<?php
$hostname = "localhost";
$username = "username";
$password = "db-password";
$dbname = "database-name";
$q = $_GET['q'];
if(isset($q) || !empty($q)) {
	$con = mysqli_connect($hostname, $username, $password, $dbname);
    $query = "SELECT * FROM stdcodes WHERE CONCAT(city, ' ', stdcode) LIKE '%$q%'";
    $result = mysqli_query($con, $query);
    $res = array();
    while($resultSet = mysqli_fetch_assoc($result)) {
	 $res[$resultSet['id']] = $resultSet['city'].", STD-CODE: ".$resultSet['stdcode'];
    }
    if(!$res) {
    	$res[0] = 'Not found!';
    }
    echo json_encode($res);
