在PHP中将对象值转换为字符串失败

我正在尝试找到一种将对象$php_object->page->ad->makeName强制转换为字符串的方法，但到目前为止，我所阅读的所有解决方案都没有为我工作。以下代码

$json_string = '{"SUPPRESS_DEALER_REPORTING_FOR_AD_IDS":[211124806],"REQUEST_LANGUAGE_SETTINGS":"de","org.springframework.validation.BindingResult.SUPPRESS_DEALER_REPORTING_FOR_AD_IDS":{"target":[211124806],"autoGrowNestedPaths":true,"autoGrowCollectionLimit":256,"objectName":"SUPPRESS_DEALER_REPORTING_FOR_AD_IDS","messageCodesResolver":{"prefix":"","formatter":"PREFIX_ERROR_CODE"},"errors":[],"suppressedFields":[],"nestedPath":"","nestedPathStack":[]},"org.springframework.validation.BindingResult.REQUEST_LANGUAGE_SETTINGS":{"target":"de","autoGrowNestedPaths":true,"autoGrowCollectionLimit":256,"objectName":"REQUEST_LANGUAGE_SETTINGS","messageCodesResolver":{"prefix":"","formatter":"PREFIX_ERROR_CODE"},"errors":[],"suppressedFields":[],"nestedPath":"","nestedPathStack":[]},"page":{"ad":{"makeName":{"value":"Volkswagen"},"modelName":{"value":"Polo"},"damagedVehicle":{"value":""},"exportVehicle":{},"countryVersion":{},"images":[{"thumbnail":{"src":"https://ssli.ebayimg.com/00/s/MTE5NFgxNjAw/z/CPkAAOSwKrhVeHwO/$_18.JPG"},"medium":{"src":"https://ssli.ebayimg.com/00/s/MTE5NFgxNjAw/z/CPkAAOSwKrhVeHwO/$_24.JPG"},"large":{"src":"https://ssli.ebayimg.com/00/s/MTE5NFgxNjAw/z/CPkAAOSwKrhVeHwO/$_27.JPG"}},{"thumbnail":{"src":"https://ssli.ebayimg.com/00/s/MTE5NFgxNjAw/z/stgAAOSweW5VeHwd/$_18.JPG"},"medium":{"src":"https://ssli.ebayimg.com/00/s/MTE5NFgxNjAw/z/stgAAOSweW5VeHwd/$_24.JPG"},"large":{"src":"https://ssli.ebayimg.com/00/s/MTE5NFgxNjAw/z/stgAAOSweW5VeHwd/$_27.JPG"}},{"thumbnail":{"src":"https://ssli.ebayimg.com/00/s/MTE5NFgxNjAw/z/nMEAAOSw~OdVeHws/$_18.JPG"},"medium":{"src":"https://ssli.ebayimg.com/00/s/MTE5NFgxNjAw/z/nMEAAOSw~OdVeHws/$_24.JPG"},"large":{"src":"https://ssli.ebayimg.com/00/s/MTE5NFgxNjAw/z/nMEAAOSw~OdVeHws/$_27.JPG"}},{"thumbnail":{"src":"https://ssli.ebayimg.com/00/s/MTE5NFgxNjAw/z/L~oAAOSwZd1VeHw5/$_18.JPG"},"medium":{"src":"https://ssli.ebayimg.com/00/s/MTE5NFgxNjAw/z/L~oAAOSwZd1VeHw5/$_24.JPG"},"large":{"src":"https://ssli.ebayimg.com/00/s/MTE5NFgxNjAw/z/L~oAAOSwZd1VeHw5/$_27.JPG"}},{"thumbnail":{"src":"https://ssli.ebayimg.com/00/s/MTE5NFgxNjAw/z/vJgAAOSwstxVeHxF/$_18.JPG"},"medium":{"src":"https://ssli.ebayimg.com/00/s/MTE5NFgxNjAw/z/vJgAAOSwstxVeHxF/$_24.JPG"},"large":{"src":"https://ssli.ebayimg.com/00/s/MTE5NFgxNjAw/z/vJgAAOSwstxVeHxF/$_27.JPG"}},{"thumbnail":{"src":"https://ssli.ebayimg.com/00/s/MTE5NFgxNjAw/z/vqcAAOSwstxVeHxU/$_18.JPG"},"medium":{"src":"https://ssli.ebayimg.com/00/s/MTE5NFgxNjAw/z/vqcAAOSwstxVeHxU/$_24.JPG"},"large":{"src":"https://ssli.ebayimg.com/00/s/MTE5NFgxNjAw/z/vqcAAOSwstxVeHxU/$_27.JPG"}},{"thumbnail":{"src":"https://ssli.ebayimg.com/00/s/MTE5NFgxNjAw/z/is4AAOSwBahVeHxk/$_18.JPG"},"medium":{"src":"https://ssli.ebayimg.com/00/s/MTE5NFgxNjAw/z/is4AAOSwBahVeHxk/$_24.JPG"},"large":{"src":"https://ssli.ebayimg.com/00/s/MTE5NFgxNjAw/z/is4AAOSwBahVeHxk/$_27.JPG"}},{"thumbnail":{"src":"https://ssli.ebayimg.com/00/s/MTE5NFgxNjAw/z/MasAAOSw3xJVeHxz/$_18.JPG"},"medium":{"src":"https://ssli.ebayimg.com/00/s/MTE5NFgxNjAw/z/MasAAOSw3xJVeHxz/$_24.JPG"},"large":{"src":"https://ssli.ebayimg.com/00/s/MTE5NFgxNjAw/z/MasAAOSw3xJVeHxz/$_27.JPG"}},{"thumbnail":{"src":"https://ssli.ebayimg.com/00/s/MTYwMFgxMTk0/z/YeMAAOSwpDdVeHyF/$_18.JPG"},"medium":{"src":"https://ssli.ebayimg.com/00/s/MTYwMFgxMTk0/z/YeMAAOSwpDdVeHyF/$_24.JPG"},"large":{"src":"https://ssli.ebayimg.com/00/s/MTYwMFgxMTk0/z/YeMAAOSwpDdVeHyF/$_27.JPG"}},{"thumbnail":{"src":"https://ssli.ebayimg.com/00/s/MTE5NFgxNjAw/z/rSwAAOSw~OdVeHyU/$_18.JPG"},"medium":{"src":"https://ssli.ebayimg.com/00/s/MTE5NFgxNjAw/z/rSwAAOSw~OdVeHyU/$_24.JPG"},"large":{"src":"https://ssli.ebayimg.com/00/s/MTE5NFgxNjAw/z/rSwAAOSw~OdVeHyU/$_27.JPG"}},{"thumbnail":{"src":"https://ssli.ebayimg.com/00/s/MTE5NFgxNjAw/z/klcAAOSwBahVeHyj/$_18.JPG"},"medium":{"src":"https://ssli.ebayimg.com/00/s/MTE5NFgxNjAw/z/klcAAOSwBahVeHyj/$_24.JPG"},"large":{"src":"https://ssli.ebayimg.com/00/s/MTE5NFgxNjAw/z/klcAAOSwBahVeHyj/$_27.JPG"}},{"thumbnail":{"src":"https://ssli.ebayimg.com/00/s/MTE5NFgxNjAw/z/s1gAAOSw~OdVeHy0/$_18.JPG"},"medium":{"src":"https://ssli.ebayimg.com/00/s/MTE5NFgxNjAw/z/s1gAAOSw~OdVeHy0/$_24.JPG"},"large":{"src":"https://ssli.ebayimg.com/00/s/MTE5NFgxNjAw/z/s1gAAOSw~OdVeHy0/$_27.JPG"}}],"internalNumber":{"link":{}},"additionalAttributes":[{"label":"Hubraum","link":{},"value":"1390 cm³"},{"label":"Anzahl Sitzplätze","link":{},"value":"5"},{"label":"Anzahl der Türen","link":{},"value":"4/5"},{"label":"Schadstoffklasse","link":{},"value":"Euro4"},{"label":"Umweltplakette","link":{},"value":"4 (Grün)"}],"genericFeatures":{"headline":{},"features":[],"available":false},"interiorFeatures":{"headline":{"value":"Innenausstattung"},"features":[{"value":"CD-Spieler","enabled":true},{"value":"Einparkhilfe (Hinten)","enabled":true},{"value":"Elektr.

返回

array (size=1)
  0 => 
    array (size=3)

          public 'value' => string 'Volkswagen' (length=10)

有经验的人可以支持找到解决方案。

非常感谢提前！

尝试

$php_object = json_decode($json_string,true);

$adDetails = array();
//pr($php_object);
if(!empty($php_object['page']['ad']['makeName'])) {

    $adDetails[] = array(   "fk_adId" => $php_object['page']['ad']['adId'],
                            "property" => 'makeName',
                            "value" => $php_object['page']['ad']['makeName'],
                            );
}
echo "<pre>";
var_dump($adDetails);

说明：

在这里，您要将一个json字符串转换为对象数组，您需要做的是在json_decode($json_string,true)中传递一个额外的参数true，它会为您提供一个数组，并且它就是

答案 1 :(得分：0)

第二个参数将解码的json字符串转换为关联数组。

示例：

json_decode('{"foo":"bar"}'); // returns an object, not an array.
json_decode('{"foo":"bar"}', true); // returns array("foo" => "bar")

您可以详细了解here。

您使用的是json_decode($json_string)，它是返回对象格式而不是数组格式。

现在，我希望您了解如何将JSON值转换为PHP数组。请将以下代码替换为您的代码并完成。

//Decode JSON data to PHP array
$php_array = json_decode($json_string, TRUE);

//Initialize array
$adDetails = array();

//Check for array value is not empty
if(!empty($php_array['page']['ad']['makeName'])) {

    //Set array value
    $adDetails[] = array("fk_adId" => $php_array['page']['ad']['adId'],
                            "property" => 'makeName',
                            "value" => $php_array['page']['ad']['makeName'],
                            );
}

//Remove print stuff if not require
print('<pre>');
print_r($adDetails);
print('</pre>');

上面的代码将返回你想要的PHP数组，打印如下：

Array
(
    [0] => Array
        (
            [fk_adId] => 211124806
            [property] => makeName
            [value] => Array
                (
                    [value] => Volkswagen
                )

        )

)
