需要JSON短语php数组的帮助吗

我在PHP中解析JSON时遇到一些困难，请帮助我如何使用PHP显示JSON项的“closePrice”

我试着通过循环数组来表达语法，但我不明白

JSON数据：

我尝试了下面的代码，但没有成功

$obj = json_decode($json, true);

foreach ($obj as $item) {
    foreach ($item as $data) {
        foreach ($data as $d) {
            echo $d['closePrice'];
        }
    } 
}

请帮帮我

问候,， Ashok

试试这个

$arrJson = json_decode($strJson);
echo $arrJson->data[0]->closePrice;

---

$obj['data'][0]['closePrice']

有什么问题？
