if(!function_exists('getTableWhere')) {

    function getTableWhere($table,$where) {
        $data = DB::table($table)
            ->select(DB::raw('*'))
            ->where($where)
            ->first();
        return $data;
    }
}

?>

        "files": [
    "app/helper.php"
],

{
  public function index()
  {
	$where= array('id'=>$product->product_category_id); 
	$data = getTableWhere('categories',$where); 
	
	echo "<pre>";
	print_r($data);
	echo "</pre>"; die;
	
    return view('product.view', compact('result','data'));
  }
