Hi All ,

I use xampp and laravel for my application. Database use Mssql. when open our app it show error
PDOException

could not find driver

public function createConnection($dsn, array $config, array $options)
{
$username = array_get($config, 'username');
$password = array_get($config, 'password');
return new PDO($dsn, $username, $password, $options);
}

I enable extension in php.ini , but it still error. how can I fix it.
