Immediately, i we’ll present you laravel eight a number of database connection instance. This text gives you easy instance of laravel eight a number of database connection instance.

you’ll laravel eight a number of database connection instance. On this article, we’ll implement a laravel eight a number of database connection instance.

So let’s observe few step to create instance of laravel eight a number of database connection instance.

Set ENV File

it’s essential set configuration variable on .env file.
.env

DB_CONNECTION=mysql
DB_HOST=127.0.0.1
DB_PORT=3306
DB_DATABASE=mydatabase

            ]) : [],
        ],
        'mysql2' => [
            'driver' => env('DB_CONNECTION_SECOND'),
            'host' => env('DB_HOST_SECOND', '127.0.0.1'),
            'port' => env('DB_PORT_SECOND', '3306'),
            'database' => env('DB_DATABASE_SECOND', 'forge'),
            'username' => env('DB_USERNAME_SECOND', 'forge'),
            'password' => env('DB_PASSWORD_SECOND', ''),
            'unix_socket' => '',
            'charset' => 'utf8mb4',
            'collation' => 'utf8mb4_unicode_ci',
            'prefix' => '',
            'prefix_indexes' => true,
            'strict' => true,
            'engine' => null,
        ],

Use Database A number of Connection:

Database Reference to migration
Default:

<?php

public operate up()
{
    Schema::create('weblog', operate (Blueprint $desk) {
        $table->increments('id');
        $table->string('title');
        $table->string('physique')->nullable();
        $table->timestamps();
    });
}

Second Database Connection:

<?php

public operate up()
{
    Schema::connection('mysql2')->create('weblog', operate (Blueprint $desk) {
        $table->increments('id');
        $table->string('title');
        $table->string('physique')->nullable();
        $table->timestamps();
    });
}

Database Reference to mannequin

Default:

<?php
namespace App;
use IlluminateDatabaseEloquentModel;

class Weblog extends Mannequin
{
}

Second:

<?php
namespace App;
use IlluminateDatabaseEloquentModel;

class Weblog extends Mannequin
{
    protected $connection = 'mysql2';
}

Database Connection in Controller
Default:

<?php
class BlogController extends BaseController
{
    public operate getRecord()
    {
        $blogModel = new Weblog;
        $discover = $blogModel->discover(1);
        return $discover;
    }
}

Second:

<?php

class BlogController extends BaseController
{
    public operate getRecord()
    {
        $blogModel = new Weblog;
        $blogModel->setConnection('mysql2');
        $discover = $blogModel->discover(1);
        return $discover;
    }
}

Database Reference to Question Builder
Default:

$blogs = DB::desk("weblog")->get();
print_r($blogs);

Second:

$blogs = DB::connection('mysql2')->desk("weblog")->get();
print_r($blogs);

I hope it is going to help you…
