数组与对象的转换

//php 对象到数组转换
    private function objToArr($obj){
        if(!is_object($obj) && !is_array($obj)) {
            return $obj;
        }
        $arr = array();
        foreach($obj as $k => $v){
            $arr[$k] = $this->objToArr($v);
        }
        return $arr;
    }
   
    //简单实现json到php数组转换功能
    private function simple_json_parser($json){
        $json = str_replace("{","",str_replace("}","", $json));
        $jsonValue = explode(",", $json);
        $arr = array();
        foreach($jsonValue as $v){
            $jValue = explode(":", $v);
            $arr[str_replace('"',"", $jValue[0])] = (str_replace('"', "", $jValue[1]));
        }
        return $arr;
    }
