Error 400 Bad Request details

[ramalingam07]

I tested all examples & will go to 400 error only. Sample to what I tested code,
/azure-sdk-for-php-master/examples/MediaServices/analyticsworkflow_indexer.php

My error:

Azure SDK for PHP - Media Analytics Sample (Indexer)
Fatal error: Uncaught WindowsAzure\Common\ServiceException: Fail: Code: 400 Value: Bad Request details (if any): {"error":{"code":"MissingApiVersionParameter","message":"The api-version query parameter (?api-version=) is required for all requests."}}. in C:\xampp\htdocs\azure_sdk\azure-sdk-for-php-master\vendor\microsoft\windowsazure\src\Common\Internal\Http\HttpClient.php:405 Stack trace: #0 C:\xampp\htdocs\azure_sdk\azure-sdk-for-php-master\vendor\microsoft\windowsazure\src\Common\Internal\Http\HttpClient.php(301): WindowsAzure\Common\Internal\Http\HttpClient::throwIfError(400, 'Bad Request', Object(GuzzleHttp\Psr7\Stream), Array) #1 C:\xampp\htdocs\azure_sdk\azure-sdk-for-php-master\vendor\microsoft\windowsazure\src\Common\Internal\RestProxy.php(144): WindowsAzure\Common\Internal\Http\HttpClient->sendAndGetHttpResponse(Array, Object(WindowsAzure\Common\Internal\Http\Url)) #2 C:\xampp\htdocs\azure_sdk\azure-sdk-for-php-master\vendor\microsoft\windowsazure\src\Common\Internal\ServiceRestProxy.php(89): WindowsAzure\Common in C:\xampp\htdocs\azure_sdk\azure-sdk-for-php-master\vendor\microsoft\windowsazure\src\Common\Internal\Http\HttpClient.php on line 405
