How to use multiple databases in Laravel

There are the Following The simple About How to use multiple databases in Laravel Full Information With Example and source code.

As I will cover this Post with live Working example to develop laravel 5.8 connect to multiple databases, so the laravel using multiple database connections for this example is following below.

  javascript Form validation Source code

Using .env >= 5.0 (tested on 5.6)

In .env file settings

DB_CONNECTION=mysql
DB_HOST=127.0.0.1
DB_PORT=3306
DB_DATABASE=pakainfo
DB_USERNAME=modi_information
[email protected]

DB_CONNECTION_SECOND=mysql
DB_HOST_SECOND=127.0.0.1
DB_PORT_SECOND=3306
DB_DATABASE_SECOND=atmiya
DB_USERNAME_SECOND=modi_information
[email protected]

step 2: In config/database.php

'mysql' => [
    'driver'    => env('DB_CONNECTION'),
    'host'      => env('DB_HOST'),
    'port'      => env('DB_PORT'),
    'database'  => env('DB_DATABASE'),
    'username'  => env('DB_USERNAME'),
    'password'  => env('DB_PASSWORD'),
],

'mysql2' => [
    'driver'    => env('DB_CONNECTION_SECOND'),
    'host'      => env('DB_HOST_SECOND'),
    'port'      => env('DB_PORT_SECOND'),
    'database'  => env('DB_DATABASE_SECOND'),
    'username'  => env('DB_USERNAME_SECOND'),
    'password'  => env('DB_PASSWORD_SECOND'),
],

IMP Note:In Laravel mysql2 if DB_username as well as DB_password is same, after that We can use simple env(‘DB_USERNAME’) which is here metioned in .env first few some lines.

Laravel Multiple db config Without .env <5.0

app/config/database.php

return array(

    'default' => 'mysql',

    'connections' => array(

        # Primary/Default database connection
        'mysql' => array(
            'driver'    => 'mysql',
            'host'      => '127.0.0.1',
            'database'  => 'pakainfo',
            'username'  => 'modi_information',
            'password'  => '[email protected]'
            'charset'   => 'utf8',
            'collation' => 'utf8_unicode_ci',
            'prefix'    => '',
        ),

        # Laravel Secondary database connection
        'mysql2' => array(
            'driver'    => 'mysql',
            'host'      => '127.0.0.1',
