I am creating a multi-tenant application in which, based on the sub-domain, I am connecting to a database of that particular tenant.

Here is code to do that:

    // To connect with a subdomain - the entry will be in config/database.php.
    public static function connectSubdomainDatabase($dbname)
    {
        $res = DB::select("show databases like '{$dbname}'");
        if (count($res) == 0) {
            App::abort(404);
        }
        Config::set('database.connections.subdomain.database', $dbname);

        //If you want to use query builder without having to specify the connection
        Config::set('database.default', 'subdomain');
        DB::reconnect('subdomain');
     }

Is it the best way to connect with a database or is there any problem that because I am thinking from the performance point of view because every time I am connecting with the database when there are different subdomains. What is the best possible way to do that?

This is nearly the best way to do this. In the end, it's all opinion anyway. However, I would create a connection in the configuration file for each of the subdomains. Then, in your connectSubdomainDatabase() function, I would get the current subdomain instead of passing a database name. You can already specify a connection in laravel, the only place you should be using database names is in the config file.

So, something like this:

// To connect with a subdomain - the entry will be in config/database.php.
public static function connectSubdomainDatabase()
{
    // Break apart host
    $urlParts = explode('.', $_SERVER['HTTP_HOST']);

    // Change default connection
    Config::set('database.default', $urlParts[0]);
 }

Where the config/database.php connections is:

'connections' => [

        'subdomain1' => [
            'driver'    => 'mysql',
            'host'      => env('DB_HOST', 'localhost'),
            'database'  => env('DB_DATABASE', 'forge'),
            'username'  => env('DB_USERNAME', 'forge'),
            'password'  => env('DB_PASSWORD', ''),
            'charset'   => 'utf8',
            'collation' => 'utf8_unicode_ci',
            'prefix'    => '',
            'strict'    => false,
        ],

        'subdomain2' => [
                'driver'    => 'mysql',
                'host'      => env('DB_HOST', 'localhost'),
                'database'  => env('DB_DATABASE', 'forge'),
                'username'  => env('DB_USERNAME', 'forge'),
                'password'  => env('DB_PASSWORD', ''),
                'charset'   => 'utf8',
                'collation' => 'utf8_unicode_ci',
                'prefix'    => '',
                'strict'    => false,
        ],

    ],
