无法通过 PHP 向现有 json 数组添加值。没有什么帮助

  • 772

伙计们，翻遍了一切。放弃神经。请告诉我。

有一个像这样的数组

{
    "0": {
        "id": 666
    },
    "status": "ok",
    "timestamp": 1541259393211,

我需要向所有子数组添加一个值为 0 的新键。

我知道这并不难，但我已经尝试了一切。还有 unshift 和 slice 以及一些已经很愚蠢的选项，但仍然没有任何结果。请帮帮我。

    $array = json_decode($str, true);

for ($i = 0; $i < count($array['data']); $i++){
    $array['data'][$i]['newKey'] = 0;
}

    您应该在哪里newKey添加您的密钥。

    好吧，因此，$str您的字符串在变量中json
