php - PHP - 对象和数组 - 如何访问数组内的 stdClass 对象“名称”“值”对？

Question

我想知道如何使用数组内的名称值对返回对象的值。我一直在尝试各种方法，坦率地说，我意识到我可能在这方面太过分了。我需要一些帮助来尝试在属性数组中获取 AirportsInformation_DataExtension 值。

stdClass Object

                                )

                            [23] => stdClass Object
                                (
                                    [Name] => EmailID
                                    [Value] => 44388
                                )

                        )

                )

        )

)

使用 foreach 循环，我能够打印出所有带有名称/值集的行

foreach ($results->Results->Properties->Property as $CurrentProp){
    print('<br>');
    print('Name: '.$CurrentProp->Name. ' Value: '.$CurrentProp->Value.'<br>');                    
};

可悲的是我无法通过那个。我只需要检索值。提前致谢。

Answer 1

为了获取值，您可以遍历它们并测试名称匹配AirportsInformation_DataExtension：

foreach ($results->Results->Properties->Property as $CurrentProp){

    if($CurrentProp->Name == 'AirportsInformation_DataExtension')
    {
        echo 'The value is: ' . $CurrentProp->Value;
    }

}

Answer 2

使用 MrCode 的上述解决方案，或者只使用$results->Results->Properties->Property[15]->Valueif 的索引AirportsInformation_DataExtensionalways 15。由于数组是ordered列表，因此索引很可能不会更改，除非从数组中删除/添加某些项目/

Answer 3

如果您需要能够根据名称获取所有值，则将其转换为关联数组可能会很有用，如下所示

$results->Results->Properties->PropertyArray = array();
foreach($results->Results->Properties->Property as $arrCurrentProperty) {
  $results->Results->Properties->PropertyArray[$arrCurrentProperty->Name] = $arrCurrentProperty->Value;
};

然后您可以稍后通过直接索引它们来获取值，即

echo 'The value is: ' . $results->Results->Properties->PropertyArray['AirportsInformation_DataExtension'];

Answer 4

foreach ($results->Results->Properties->Property as $CurrentProp){
    $tempArr[$CurrentProp->Name] = $CurrentProp->Value;
}

echo $tempArr['AirportsInformation_DataExtension'];

通过这个，您可以访问该对象的任何其他键。
