Connection to MS SQLServer

I configure php.ini to connect to sqlserver, added needed extension :

extension=php_sqlsrv_74_nts_x64.dll

extension=php_pdo_sqlsrv_74_nts_x64.dll

and extension loaded it is OK , MS Sql server installed and TCP port is open,

.env file and database.php file configed like these:

'sqlsrv' => [ 'driver' => 'sqlsrv', 'host' => env('DB_HOST', 'localhost'), 'port' => env('DB_PORT', '1433'), 'database' => env('DB_DATABASE', 'xxx'), 'username' => env('DB_USERNAME', 'xxx'), 'password' => env('DB_PASSWORD', 'xxx'), 'charset' => 'utf8', 'prefix' => '', 'prefix_indexes' => true, ],

DB_CONNECTION=sqlsrv DB_HOST=localhost DB_PORT=1433 DB_DATABASE=xxx DB_USERNAME=xxx DB_PASSWORD=xxx

but this is error encountered when I want to select something : "driver not found"

or if I run "php artisan migrate" I have this ERROR :

Illuminate\Database\QueryException

could not find driver (SQL: select * from information_schema.tables where table_schema = laravel and table_name = migrations and table_type = 'BASE TABLE')

at C:\inetpub\test1\vendor\laravel\framework\src\Illuminate\Database\Connection.php:671 667| // If an exception occurs when attempting to run a query, we'll format the error 668| // message to include the bindings with SQL, which will make this exception a 669| // lot more helpful to the developer instead of just the database's errors. 670| catch (Exception $e) { 671| throw new QueryException( 672| $query, $this->prepareBindings($bindings), $e 673| ); 674| } 675|
