类＆＃39; net \ authorize \ api \ contract \ v1 \ MerchantAuthenticationType＆＃39;找不到authorize.net

Question

我在php中的项目中集成了Authorize.net支付网关。但在这里我收到了以下错误。

  

致命错误：类＆＃39; net \ authorize \ api \ contract \ v1 \ MerchantAuthenticationType＆＃39;在第13行的C：\ xampp \ htdocs \ anurag \ sdk-php-master \ sample-code-php-master \ PaymentTransactions \ charge-credit-card.php中找不到

我的代码如下 -
