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;
}
