You might need to use these:

use Illuminate\Support\Facades\Config;
use DB;

Set database configurations:

        Config::set("database.connections.mysql_external", [
            'driver' => 'mysql',
            "host" => "localhost",
            "database" => "db_name",
            "username" => "root",
            "password" => "root",
            "port" => '8889',
            'charset'   => 'utf8',
            'collation' => 'utf8_unicode_ci',
            'prefix'    => '',
            'strict'    => false,
        ]);

Connect to database and do stuff:

    $users = DB::connection('mysql_external')->select('Select id from users');

Disconnect database and reset config variables

        DB::disconnect('mysql_external');
        Config::set("database.connections.mysql_external", [
            'driver' => 'mysql',
            "host" => "localhost",
            "database" => "",
            "username" => "",
            "password" => "",
            "port" => '',
            'charset'   => 'utf8',
            'collation' => 'utf8_unicode_ci',
            'prefix'    => '',
            'strict'    => false,
        ]);
