写一个PHP将对象转换为数据的函数

// 对象转换为数组
function obj2arr($obj){
$result = array();
if(!is_array($obj)){
if($var = get_object_vars($obj)){
foreach($var as $key => $value){
$result[$key] = obj2Arr($value);
            }
        } else{
return $obj;
        }
    } else{
foreach($obj as $key => $value){
$result[$key] = obj2Arr($value);
        }
    }
return $result;
}
