XML to JSON conversion in php

            $data = "<QRYRESULT>
            <ISSUCCESS>Y</ISSUCCESS>
            <EBLCUSTOMER ACCOUNTNO='11111'>
            <CUSTACCTNO>121212</CUSTACCTNO>
            <ACCTSTATUS>active</ACCTSTATUS>
            <CCYDESC>BDT</CCYDESC>
            <BALANCE>9999</BALANCE>
            <AVAILABLEBALANCE>99</AVAILABLEBALANCE>
            <CUSTOMERNAME>cus_name</CUSTOMERNAME>
            <AMOUNTONHOLD>1000</AMOUNTONHOLD>
            <ODLIMIT>99</ODLIMIT>
            </EBLCUSTOMER>
            </QRYRESULT>";

this is the XML string I am trying to convert. I have used the folloung code.

           $result = str_replace(array("\n", "\r", "\t"), '', $data);
           $xml = simplexml_load_string($result);
           $object = new stdclass();
           $object->webservice[] = $xml;
           $result = json_encode($object);
           header('content-Type: application/json');
           echo $result;

And I am getting the following json data.

  {
     "webservice": [
       {
        "ISSUCCESS": "Y",
        "CUSTSUMMARY": {
            "@attributes": {
                "ACCOUNT": "11111"
            },
            "IDACCOUNT": "1010101",
            "CODACCTCURR": "BDT",
            "NUMBALANCE": "99999",
            "ACCTDESC": "22222",
            "PRDNAME": "name"
            }
         }
      ]
   }

But i don't want the "@attributes". I want the output like below:

{
  "QRYRESULT": {
   "ISSUCCESS": "Y",
   "EBLCUSTOMER": {
    "-ACCOUNTNO": "11111",
    "CUSTACCTNO": "121212",
    "ACCTSTATUS": "active",
    "CCYDESC": "BDT",
    "BALANCE": "9999",
     "AVAILABLEBALANCE": "99",
     "CUSTOMERNAME": "cus_name",
     "AMOUNTONHOLD": "1000",
    "ODLIMIT": "99"
    }
   }
  }

How can I do that ??
