如何JSON解码的多维阵列

Question

我有一个数组包含JSON在一些索引，我有将其解码

例如：

这是JSON

$json = {"Lavel1":"This is Lavel1","LavelLoop":"{\"Lavel2\":\"This is Lavel2\",\"LavelLoop\":\"{\\\"Lavel3\\\":\\\"This is Lavel3\\\",\\\"LavelLoop\\\":[]}\"}"} 

如果是第一次解码，那么它给这个数组

$array = json_decode($json); 

// this is the output 
Array 
(
    [Lavel1] => This is Lavel1 
    [LavelLoop] => {"Lavel2":"This is Lavel2","LavelLoop":"{\"Lavel3\":\"This is Lavel3\",\"LavelLoop\":[]}"} 
) 

所以我有解码了三次，但我不能假设它有多少次JSON包含

欲望输出应该是这样的

Array 
(
    [Lavel1] => This is Lavel1 
    [LavelLoop] => Array 
     (
      [Lavel2] => This is Lavel2 
      [LavelLoop] => Array 
       (
        [Lavel3] => This is Lavel3 
        [LavelLoop] => Array 
         (
         ) 
       ) 
     ) 
) 

我试过循环，但它不工作，它给了我像一些索引显示错误n me empty

Answer 1

我已经更新了答案看看再次

$json = '{"Lavel1":"This is Lavel1","LavelLoop":"{\"Lavel2\":\"This is Lavel2\",\"LavelLoop\":\"{\\\"Lavel3\\\":\\\"This is Lavel3\\\",\\\"LavelLoop\\\":[]}\"}"}'; 

$array = nested_jsonDecode($json, true); 

print_r($array); 


function nested_jsonDecode($string, $is_array = true){ 
    return is_bool($is_array) 
     ? json_decode(str_replace(['\\','"[',']"','"{', '}"'], ['','[',']','{', '}'],$string), $is_array) 
     : ''; 
} 

输出

Array 
(
    [Lavel1] => This is Lavel1 
    [LavelLoop] => Array 
     (
      [Lavel2] => This is Lavel2 
      [LavelLoop] => Array 
       (
        [Lavel3] => This is Lavel3 
        [LavelLoop] => Array 
         (
         ) 

       ) 

     ) 

)

LaravelLoop是一个字符串，而不是一个对象。对所有人来说都是这样。删除引号，它会解码罚款。
