Let’s get started.


Installation of Laravel Application

Laravel Installation can be done in two ways.

  • Laravel Installer
  • By using composer

Laravel Installer

To install Laravel via Laravel installer, we need to install it’s installer first. We need to make use of composer for that.

$ composer global require laravel/installer

This command will install laravel installer at system. This installation is at global scope, so you type command from any directory at terminal. To verify type the given command –

$ laravel

This command will open a command palette of Laravel Installer.

To create ad install laravel project in system,

$ laravel new blog

With the name of blog a laravel project will be created at your specified path.

By using composer

Alternatively, we can also install Laravel by Composer command create-project. If your system doesn’t has Composer Installed, Learn Composer Installation Steps. Here is the complete command to create a laravel project-

$ composer create-project --prefer-dist laravel/laravel blog

After following these steps we can install a Laravel application into system.

To start the development server of Laravel –

$ php artisan serve

This command outputs –

Starting Laravel development server: http://127.0.0.1:8000

Assuming laravel already installed at system.


Create Database & Connect

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

CREATE DATABASE laravel_app;

To connect database with application, Open .env file from application root. Search for DB_ and update your details.

DB_CONNECTION=mysql
DB_HOST=127.0.0.1
DB_PORT=3306
DB_DATABASE=laravel_app
DB_USERNAME=root
DB_PASSWORD=root

Create Model & Migration

Open project into terminal and run this command to create model & migration file.

$ php artisan make:model Country -m

It will create two files –

  • Model – Country.php at /app/Models folder
  • Migration file – 2021_07_25_123805_2021_08_10_120110_create_countries_table at /database/migrations folder.

Open Migration file and write this complete code into it.

<?php

use Illuminate\Database\Migrations\Migration;
use Illuminate\Database\Schema\Blueprint;
use Illuminate\Support\Facades\Schema;

class CreateCountriesTable extends Migration
{
    /**
     * Run the migrations.
     *
     * @return void
     */
    public function up()
    {
        Schema::create('countries', function (Blueprint $table) {
            $table->increments('id');
            $table->string('sortname');
            $table->string('name');
            $table->string('phonecode');
        });
    }

    /**
     * Reverse the migrations.
     *
     * @return void
     */
    public function down()
    {
        Schema::dropIfExists('countries');
    }
}

Open model file Country.php and write this complete code into it.

<?php

namespace App\Models;

use Illuminate\Database\Eloquent\Factories\HasFactory;
use Illuminate\Database\Eloquent\Model;

class Country extends Model
{
    use HasFactory;

    public $timestamps = false;
}

Run Migration

Next, we need to create table inside database.

$ php artisan migrate

Prepare CSV File

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

We will take a CSV file in which the columns 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 .csv and place this countries.csv file inside /public/data folder.

Open countries.csv file, you should see –


Create Seeder

Next, we need to create a seeder file.

$ php artisan make:seeder CountrySeeder

It will create a file CountrySeeder.php at /database/seeders folder.

Open CountrySeeder.php and write this complete code into it.

<?php

namespace Database\Seeders;

use Illuminate\Database\Seeder;
use App\Models\Country;

class CountrySeeder extends Seeder
{
    /**
     * Run the database seeds.
     *
     * @return void
     */
    public function run()
    {
        Country::truncate();

        $csvFile = fopen(public_path("data/countries.csv"), "r");

        $firstline = true;
        while (($data = fgetcsv($csvFile, 2000, ",")) !== FALSE) {
            if (!$firstline) {
                Country::create([
                    "sortname" => $data['1'],
                    "name" => $data['2'],
                    "phonecode" => $data['3']
                ]);
            }
            $firstline = false;
        }

        fclose($csvFile);
    }
}

Data Seeding

Open project into terminal and run this artisan command

$ php artisan db:seed --class=CountrySeeder

It will seed countries data into table.
