Let’s get started.

Create Database & Table

To create a database, either we can create via Manual tool of PhpMyadmin or by means of a mysql command.

CREATE DATABASE php_applications;

Inside this database, we need to create a table.

Table we need – countries

CREATE TABLE `countries` (
 `name` varchar(120) NOT NULL,
 `sortname` varchar(10) NOT NULL,
 `phonecode` varchar(20) NOT NULL,

Dummy Data for Application

As we have table countries in which columns as id, name, sortname, phonecode.

We will take a JSON file in which properties of each object will be ID, Sortname, Name & Phonecode. Rest we need data into it.

When you will download the given file it will be in .txt format. Rename file into .json and place this countries.json file inside folder.

Application Folder Structure

You need to create a folder structure to develop this application in PHP and MySQLi. Have a look the files and folders inside this application –

Create a folder with name php-mysqli-json and create these 2 files into it.

Database Configuration

Open dbconfig.php file from folder. Add these lines of code into it.

// Database configuration
$host   = "localhost";
$dbuser = "admin";
$dbpass = "Admin@123";
$dbname = "php_applications";

// Create database connection
$conn = new mysqli($host, $dbuser, $dbpass, $dbname);

// Check connection
if ($conn->connect_error) {
    die("Connection failed: " . $conn->connect_error);

Application Programming

Open index.php file and write this following code into it.

// Include the database file
require 'dbconfig.php';

$data = [];

$json = file_get_contents("countries.json");
$countries_data = json_decode($json);

foreach ($countries_data->countries as $key => $value) {
    $data[] = [
        "sortname" => $value->sortname,
        "name" => $value->name,
        "phonecode" => $value->phoneCode

// echo "<pre>";
// print_r($data);

if (!empty($data) && count($data) > 0) {

    foreach ($data as $country) {

        $stmt = $conn->prepare("INSERT INTO countries (name, sortname, phonecode) VALUES(?, ?, ?)");
        $stmt->bind_param("sss", $country['name'], $country['sortname'], $country['phonecode']);
