I am working on below code and want the output as described the below.

     foreach($servicecategory as $servicecategory1) {
            $getcat = $objcat->Get_Category($servicecategory1);
            $employee = array(
            'category_id'=>mysql_real_escape_string($getcat['id']),
            'category_name'=>mysql_real_escape_string($getcat['catname']),
            'category_image_url'=>"",    
            'subcategory'=>array()

            );

            $getsubcat = $objcat->getCategoriesAdminNew($servicecategory1);

        foreach($getsubcat as $getsubcat1)
        {
            $getcat = $objcat->Get_Category($getsubcat1['id']);    
            $employee['subcategory'][]= array(
            'category_id'=>mysql_real_escape_string($getcat['id']),
            'category_name'=>mysql_real_escape_string($getcat['catname']),                
             'vendor_products_details' =>array()
            );


          $getproduct = $objuser->VendorProductDetailsNew2($userinfo['profile_id'],$getcat['id']);
            foreach($getproduct as $getproducts){
                $getcat = $objcat->Get_Category($getproducts['subcat_id']);
            $employee['vendor_products_details'][] = array(
            'product_id' => $getproducts['id'],
            'product_name' => $getproducts['pname'],
            'Price' => $getproducts['price'],                

            );
            }

        }

it display the output like below

  {
    "category_id": "1",
    "category_name": "Dry Cleaning",
    "category_image_url":"",
    "subcategory": [
      {
        "sub_category_id": "4",
        "sub_category_name": "Men",
        "vendor_products_details": [

        ]
      },
      {
        "sub_category_id": "5",
        "sub_category_name": "Women",
        "vendor_products_details": [

        ]
      },
      {
        "category_id": "6",
        "category_name": "Kids",
        "vendor_products_details": [

        ]
      }
    ],
    "vendor_products_details": [
      {
        "product_id": "19",
        "product_name": "T Shirt",
        "Price": "20"
      },
      {
        "product_id": "20",
        "product_name": "Top",
        "Price": "15"
      },
      {
        "product_id": "18",
        "product_name": "T shirt",
        "Price": "15"
      },
      {
        "product_id": "9",
        "product_name": "Bedsheet",
        "Price": "15"
      }
    ]
  },

    "category_id": "1",
    "category_name": "Dry Cleaning",
    "category_image_url": "",
    "subcategory": [
      {

        "sub_category_name": "Men",
        "vendor_products_details": [
          {
        "product_id": "19",
        "product_name": "T Shirt",
        "Price": "20"
      },
      {
        "product_id": "20",
        "product_name": "Top",
        "Price": "15"
      }
        ]
      },
      {
        "sub_category_id": "5",
        "sub_category_name": "Women",
        "vendor_products_details": [
          {
        "product_id": "18",
        "product_name": "T shirt",
        "Price": "15"
      },
      {
        "product_id": "9",
        "product_name": "Bedsheet",
