I Want To Install API On Xampp
I have installed and configured ssl and curl on xampp too.
after run 'composer require "jaggedsoft/php-binance-api @dev"' I created Index.php with blow codes:

require 'vendor\autoload.php';
$api_key = "my api key";
$api_secret = "my secret key";
$api = new Binance\API($api_key, $api_secret);
$result = $api->marketBuy( "BNBBTC", 1 );
print_r( $result ) . "\n";

but I have This Error:
Fatal error: Uncaught Exception: Curl error: Failed to connect to api.binance.com port 443: Connection refused in E:\xampp8\htdocs\binance\vendor\jaggedsoft\php-binance-api\php-binance-api.php:1032 Stack trace: #0 E:\xampp8\htdocs\binance\vendor\jaggedsoft\php-binance-api\php-binance-api.php(1133): Binance\API->httpRequest('v3/order', 'POST', Array, true) #1 E:\xampp8\htdocs\binance\vendor\jaggedsoft\php-binance-api\php-binance-api.php(315): Binance\API->order('BUY', 'BNBBTC', 1, '0.00000000', 'MARKET', Array) #2 E:\xampp8\htdocs\binance\index.php(10): Binance\API->marketBuy('BNBBTC', 1) #3 {main} thrown in E:\xampp8\htdocs\binance\vendor\jaggedsoft\php-binance-api\php-binance-api.php on line 1032
