ready! API This tool inside called interface, what format do I use in PHP to pass the parameter?

The right red box is where I don't know how to preach,
This is in the form of XML.

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);}

$ezidebitRequest don't know the corresponding ready! here. What format does the API tool use to pass values?
It is wrong of me to $ezidebitrequest the wording here.
