PHP数组和对象相互转化,stdClass Object转array

数组转JSON

PHP json_encode() 用于对变量进行 JSON 编码,该函数如果执行成功返回 JSON 数据,否则返回 FALSE 。

JSON转数组

PHP json_decode() 函数用于对 JSON 格式的字符串进行解码,并转换为 PHP 变量。

 $arr = array('a' => 1, 'b' => 2, 'c' => 3, 'd' => 4, 'e' => 5);
 echo json_encode($arr);
Copy after login

结果:   {"a":1,"b":2,"c":3,"d":4,"e":5} 

反之亦然。

第三方接口解析(stdClass Object转array)

最近开发商城,使用到了物流的第三方API接口的JSON数据,往往单纯通过json_decode方法解析获得得数值一般并非数组,

而是带有stdClass Objec的对象字符串,这时如果我们想获取相应的PHP数组时,需通过以下几种方法来获取。

//PHP stdClass Object转array  
function object_array($array) {  
    if(is_object($array)) {  
        $array = (array)$array;  
     } if(is_array($array)) {  
         foreach($array as $key=>$value) {  
             $array[$key] = object_array($value);  
             }  
     }  
     return $array;  
}
Copy after login

因为json_decode()函数可以接受两个参数:

当 $data= json_decode($object);  //得到的是 object 上面数据类型。

当 $data= json_decode($object, ture);  //得到的则是数组。

 $data= json_decode($json, ture);
Copy after login

本人使用的是第二种,简单也方便,打印数据

print_array($data);
Copy after login

这样就和平常的数组一样了,也方便使用了,例:

echo $data['data'][0]['traces'][0]['desc'];//[上海市] [嘉定]的震徽电子已收件 电话:暂无
