Ready! The API called in this tool. In PHP, in what format do I use to transmit parameters?

On the right side of the red box, I don't know how to upload it. This is in XML format. This is my code: {code...} $ ezidebitRequest. I don't know the corresponding Ready! What format does the API Tool use to transmit values? $ EzidebitRequest is incorrectly written here.

I don't know how to transfer it in the red box on the right,
This is in XML format.

Here is my code:

function CreditCardChargeAction(){   $ezidebit_client = new \SoapClient("http://ws.cardcall.com.au:8092/CreditCardCharge.svc?WSDL");   $ezidebitRequest = array("biz"=>array("BizID"=>"5","ClientIP"=>"101.178.140.96","HttpReferer"=>"https://www.hellophonecards.com.au/hpchome/recharge.aspx",               "BMUserAdminID"=>"1","GMUserAdminID"=>"1","Reason"=>"TPC","CardName" => "1147725","CardNumber" => "4862700011382664","CVV"=>"111",               "ExpiryYear" => "16","ExpiryMonth" => "10","Amount" => "10","Currency"=>"AUD", "SerialNo" => "CCAW0101171577","Bonus" => "0"));   $soap_result = $ezidebit_client->DoCreditCardCharge($ezidebitRequest);}

$ EzidebitRequestThe corresponding Ready is unknown here! What format does the API Tool use to transmit values?
