使用Laravel 5.7：如何從數組中獲取json值名稱？

Question

我想從JSON數組中獲取名稱值。

{
"workspaces": {
    "workspace": [
        {
            "name": "SITR",
            "href": "http://localhost:8080/geoserver/rest/workspaces/SITR.json"
        },
        {
            "name": "fire",
            "href": "http://localhost:8080/geoserver/rest/workspaces/fire.json"
        },
        {
            "name": "info-geospasial",
            "href": "http://localhost:8080/geoserver/rest/workspaces/info-geospasial.json"
        },
        {
            "name": "pertanian",
            "href": "http://localhost:8080/geoserver/rest/workspaces/pertanian.json"
        },
        {
            "name": "semangat21",
            "href": "http://localhost:8080/geoserver/rest/workspaces/semangat21.json"
        },
        {
            "name": "semangat",
            "href": "http://localhost:8080/geoserver/rest/workspaces/semangat.json"
        },
        {
            "name": "cobalagi",
            "href": "http://localhost:8080/geoserver/rest/workspaces/cobalagi.json"
        },
        {
            "name": "cobak",
            "href": "http://localhost:8080/geoserver/rest/workspaces/cobak.json"
        }
    ]
}

}

我已經嘗試了以下

$responsArray=json_decode($res->getBody());
dd($responsArray->workspaces->workspace->name);

但它返回“嘗試訪問非對象的屬性”。 有人可以幫忙嗎？ 非常感謝，謝謝

Answer 1

$nameArr = [];
$responsArray=json_decode($res->getBody());
foreach($responsArray->workspaces->workspace as $row)
{
  $nameArr[] = $row->name;
}
dd($nameArr);

Answer 2

將所有對象級別轉換為多維傳遞數組結構，並通過true標志作為json_decode()函數的第二個參數，然后像訪問多維數組一樣對其進行訪問：

$nameArr = [];
$responseArray = json_decode($res->getBody(), true); // set true here
foreach ($responseArray['workspaces']['workspace'] as $row) {
    $nameArr[] = $row['name'];
}
dd($nameArr);
