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;
}
