In Laravel, you can configure multiple databases by defining multiple database connections in your config/database.php file. Each connection can have its own configuration settings such as database name, username, password, host, and so on.

Here’s an example of how to configure multiple databases in Laravel:

1. Open the config/database.php file and locate the connections array.
2. Add a new connection to the connections array, using the following template:

bashCopy code'connection_name' => [
    'driver'    => 'mysql',
    'host'      => env('DB_HOST_connection_name', 'localhost'),
    'database'  => env('DB_DATABASE_connection_name', 'database_name'),
    'username'  => env('DB_USERNAME_connection_name', 'username'),
    'password'  => env('DB_PASSWORD_connection_name', 'password'),
    'charset'   => 'utf8',
    'collation' => 'utf8_unicode_ci',
    'prefix'    => '',
    'strict'    => true,
    'engine'    => null,
],

Replace connection_name with the name of your connection, and replace the values of DB_HOST_connection_name, DB_DATABASE_connection_name,

DB_USERNAME_connection_name, and DB_PASSWORD_connection_name with the appropriate values for your database.In your model, you can specify which connection to use by adding the following line to your model class:

phpCopy codeprotected $connection = 'connection_name';

Replace connection_name with the name of your connection.When performing database operations, you can use the desired connection by specifying the name of the connection in your query:

cssCopy codeDB::connection('connection_name')->select(...);

Replace connection_name with the name of your connection.

With these steps, you have successfully configured multiple databases in Laravel and can now work with them as needed.
