在JSON短語php數組中需要幫助

Question

我在使用PHP解析JSON時遇到一些困難，請幫助我如何使用php顯示JSON項目的“ closePrice”。

我嘗試通過循環數組進行短語表達，但沒有得到。

JSON數據：

],
"optLink": "/marketinfo/sym_map/symbolMapping.jsp?symbol=ICICIBANK&instrument=-&date=-&segmentLink=17&symbolCount=2"
}

我嘗試使用下面的代碼，但未成功。

$obj = json_decode($json, true);

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

請幫我..

問候，Ashok

嘗試這個

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