Question

我对数组不是很满意，需要一些帮助，

我只需要从这个给定的数组中专门检索“值”，例如下面这个给定数组的例子，我只需要“ 40000”值。

array:3 [▼
  0 => array:3 [▼
    "service" => "OKE"
    "description" => "Ongkos Kirim Ekonomis"
    "cost" => array:1 [▼
      0 => array:3 [▼
        "value" => 40000
        "etd" => "2-3"
        "note" => ""
      ]
    ]
  ]
  1 => array:3 [▼
    "service" => "REG"
    "description" => "Layanan Reguler"
    "cost" => array:1 [▼
      0 => array:3 [▼
        "value" => 48000
        "etd" => "1-2"
        "note" => ""
      ]
    ]
  ]
  2 => array:3 [▼
    "service" => "YES"
    "description" => "Yakin Esok Sampai"
    "cost" => array:1 [▼
      0 => array:3 [▼
        "value" => 72000
        "etd" => "1-1"
        "note" => ""
      ]
    ]
  ]
]

我一直在尝试使用array_search array_key_exists和更多的数组函数，但还是没有运气。

我以前通过这段代码已经达到了这个结果

 $costsOKE = $costObj['rajaongkir']['results'][0]['costs'][0]['cost'][0]['value']; //OKE
$costsREG = $costObj['rajaongkir']['results'][0]['costs'][1]['cost'][0]['value']; //REG
$costsYES = $costObj['rajaongkir']['results'][0]['costs'][2]['cost'][0]['value']; //YES

问题是这太静态了，因为有时它并不总是带有“ OKE”或“ YES”

我不知道如何具体检查数组的某些“键”

喜欢

if(0['service'] == 'OKE') //I already have input field for service
{
 $value = ??? //should be 40000 here and this is what I need
}

如何用最简单的方法实现这一目标？

先感谢

Laravel具有内置的辅助程序Arr::get()，用于使用“点表示法”从数组中提取嵌套值。 Laravel 6.x Arr::get() docs

use Illuminate\Support\Arr;

$costsOKE = Arr::get($costObj, 'rajaongkir.results.0.costs.0.cost.0.value');//OKE
$costsREG = Arr::get($costObj, 'rajaongkir.results.0.costs.1.cost.0.value');//REG
$costsYES = Arr::get($costObj, 'rajaongkir.results.0.costs.2.cost.0.value');//YES

或者从您提供的数组中获取：

$costsOKE = Arr::get($costObj, '0.cost.0.value');//OKE
$costsREG = Arr::get($costObj, '1.cost.0.value');//REG
$costsYES = Arr::get($costObj, '2.cost.0.value');//YES

如果该值不存在，则结果为null。

对于Laravel <= 5.6，您可以改用array_get。

如果我正确理解了您的问题，则可以尝试通过以下方式进行操作：

function leerreservas($pnr) {
    error_reporting(0);
    //ini_set('display_errors', true);
    //ini_set('display_startup_errors', true);
    $oDate = new DateTime();
    $timestamp = $oDate->format('Y-m-d\Th:i:sP');
    $timetolive = $oDate->add(new DateInterval('PT1H'))->format('Y-m-d\Th:i:sP');
    $Locator=$pnr;
    $BinarySecurityToken=selectokken(); $endpoint=selecendpoint();
    $sabre=sabredatosusuario();
    $namespaces="http://webservices.sabre.com/pnrbuilder/v1_15";

    $test = '<SOAP-ENV:Envelope

    $location_URL = $endpoint;
    $action_URL = $namespaces;
    $client = new SoapClient(null, array( 'location' => $location_URL, 'uri' => "",
    'trace' => 1, ));

    try {
        $order_return = $client->__doRequest($test,$location_URL,$action_URL,1); 
        //Get response from here
        if (empty($order_return)) {
            echo "vacio";
        } else {
            $xml2 = reemplazo($order_return);
            $xml = simplexml_load_string($xml2, 'SimpleXMLElement', LIBXML_NOCDATA);
            $datos = json_decode(json_encode($xml), TRUE);
            echo print_r($datos);
        }
    } catch (SoapFault $exception) {
        var_dump(get_class($exception));
        var_dump($exception);
    }
}

但是请注意，此功能仅适用于您的数组结构。如果结构发生变化，则可能无法正常工作。
