Php json文件中的简单数组插入

我有一个简单的json文件。这是结构

1人阵法，包含1场比赛和2场比赛阵法

我想将数据添加到匹配项[0]…第一个匹配项数组

我正在使用matchid属性，该属性必须存储在适当的匹配数组中

因此，如果我的matchid为4..我希望我的数据存储在匹配项[0][4]中。 我尝试了各种组合，但无法得到我想要的

这是我的json文件，后面是我尝试过的代码

分析错误：语法错误，意外的“[”，应为T_字符串或T_变量或“{”或“$”，我现在遇到此错误

代码2尝试

                    $inp = file_get_contents('jsontrail.json');

        $tempArray = json_decode($inp, true);
        //adding to the matchid index of matches array
        $matchid=3;
        $arrne['games']['matches'][0][$matchid]['winner'] ="winner";
        $arrne['games']['matches'][0][$matchid]['player1id'] ="player1id";
        $arrne['games']['matches'][0][$matchid]['player2id'] ="player2id";
        array_push($tempArray,$arrne );
        $jsonData = json_encode($tempArray);
        file_put_contents('jsontrail.json', $jsonData);
        print_r( $inp);

但是这会将数组推到最后。

对于初学者来说，JSON无效，有一个额外的逗号。复制并粘贴JSON到，它会告诉您出了什么问题

然后试试这个代码

<?php
$arrne = json_decode(file_get_contents('jsontrail.json'),true);
$inp = file_get_contents('jsontrail.json');
$tempArray = json_decode($inp, true);

//adding to the matchid index of matches array
$matchid = 1;
$newmatch=array();
$newmatch['winner'] ="LOOKFORME";
$newmatch['player1id'] ="player1id";
$newmatch['player2id'] ="player2id";

array_splice($tempArray["games"][0]["matches"], $matchid, 0, array($newmatch));
$jsonData = json_encode($tempArray);
file_put_contents('jsontrail.out.json', $jsonData);

---

有几件事不对：

1） 最后一个匹配项上有一个逗号：

{
  "player1id":0,
  "player2id":4,
  "winner":0
},

至少对我来说，它破坏了

json\u解码

。我用来检查格式

2） 您得到错误

致命错误：当尝试访问
$tempArray['players']['games']['matches'][0]
时，无法使用std Class类型的对象作为array

-按照JSON的设置方式，您应该这样访问它：

$tempArray->games[0]->matches[$matchid]

。但是，我认为您可能需要首先重新查看JSON的结构

3） 您正在将$tempArray['players']['games']['matches'][0][/code>传递到

array\u push

。如果您只是指匹配中的第一个元素，请将

[]

省略。请查看

我建议您将脚本的每个单独的步骤都取出，并按顺序调试每个步骤。例如，首先加载JSON，然后将其转储到屏幕上。然后对其进行解码并将其转储到屏幕上。然后尝试访问其中的元素，并将其转储到屏幕上，依此类推

祝你好运！

你确定你没有错过

$

在

arrne=json_decode

前面的一个

$

吗？哦，我在发布我的代码时留下了这个。现在将进行编辑。@AndriusNaruševičius你知道吗。。需要帮助。。不，但我试图确保你的问题更具可读性。我一年前从php切换过来，没有工具来尝试你的答案代码：）得到答案的最好运气：）我想在Plays->games->matches->0->myinputmatchid中添加数据。知道我如何实现这一点吗？谢谢你的回复他们没有玩家->游戏->比赛->0->myinputmatchid，你的数据不是那样的结构。弗洛伊德..对不起，这是游戏->比赛->0->myinputmatchid..刚刚检查过..知道吗？我知道了吗建议用新代码编辑您的原始问题，以便我们可以正确地看到代码更改。
