使用Laravel 5.7：如何从数组中获取json值名称？

Question

我想从JSON数组中获取名称值。

{
"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"
        }
    ]
}

}

我已经尝试了以下

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

但它返回“尝试访问非对象的属性”。 有人可以帮忙吗？ 非常感谢，谢谢

Answer 1

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

Answer 2

将所有对象级别转换为多维传递数组结构，并通过true标志作为json_decode()函数的第二个参数，然后像访问多维数组一样对其进行访问：

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