Question

我有一个数组，在某些索引中包含JSON，我必须解码它

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，则会给出此数组

$array = json_decode($json);

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

所以我已经解码了三次，但我不能假设它包含多少个子json

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
                        (
                        )
                )
        )
)

我已经尝试过循环，但它没有工作它给我的错误像一些索引显示我空

我已经更新了答案再看看

$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)
        : '';
}

<强>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。对所有人来说都是如此。删除引号，它将解码正常。
