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.

Tables we need – countries.

CREATE TABLE `countries` (
  `id` int(10) UNSIGNED NOT NULL,
  `name` varchar(255) COLLATE utf8mb4_unicode_ci NOT NULL,
  `sortname` varchar(255) COLLATE utf8mb4_unicode_ci NOT NULL,
  `phonecode` varchar(255) COLLATE utf8mb4_unicode_ci NOT NULL
) ENGINE=InnoDB DEFAULT CHARSET=utf8mb4 COLLATE=utf8mb4_unicode_ci;

Dummy Data for Application

Here, you need to copy mysql query from this given file and run into sql tab of phpmyadmin. First download it and run.

Download Countries Data

You will see something like this after this test data insertion.

}
