Question

首先，我是PHP的新手，所以我还在努力。我的问题是：我试图在PHP中回应Bing API结果。

这是一个JSON结果示例，我从

获取

$jsonobj = json_decode($response);

（响应是我从Bing得到的，所以我只是粘贴了下面的回复 - 只是添加这些信息，以防你想知道我从哪里获得$jsonobj = json_decode($response);）

{"d":{"results":[{"__metadata":{"uri":"https://api.datamarket.azure.com/Data.ashx/Bing/Search/Composite?Sources=\u0027web\u0027&Market=\u0027en-US\u0027&Query=\u0027php\u0027&Adult=\u0027off\u0027&$skip=0&$top=1","type":"ExpandableSearchResult"},"ID":"1c509d25-5ca4-4db5-bfc5-cafd6917e2c2","WebTotal":"10600000","WebOffset":"0","ImageTotal":"","ImageOffset":"","VideoTotal":"","VideoOffset":"","NewsTotal":"","NewsOffset":"","SpellingSuggestionsTotal":"","AlteredQuery":"","AlterationOverrideQuery":"","Web":[{"__metadata":{"uri":"https://api.datamarket.azure.com/Data.ashx/Bing/Search/ExpandableSearchResultSet(guid\u00271c509d25-5ca4-4db5-bfc5-cafd6917e2c2\u0027)/Web?$skip=0&$top=1","type":"WebResult"},"ID":"4cf2a8d6-21b7-433d-81e9-84e74091a44a","Title":"PHP: Hypertext Preprocessor","Description":"What is PHP?

现在，据我所知，我可以通过使用：

来回应WebTotal

foreach($jsonobj->d->results as $value) {
    echo $value->WebTotal;
}

但是，我对如何回应Title，Description和Url等实际结果感到迷茫。

我试过了：

foreach($jsonobj->d->results as $value) {
    echo $value->Title."<br>";
    echo $value->Description."<br>";
    echo $value->Url."<br>";
}

还有类似的东西：

foreach($jsonobj->d->results->Web as $value) {
    echo $value->Title."<br>";
    echo $value->Description."<br>";
    echo $value->Url."<br>";
}

因为我认为将网络添加到foreach可能会回应正确的值，但没有成功。

也许有人可以帮助我并告诉我我做错了什么？

我的任务是获得以下结果：

然后，另外两个结果。

非常感谢你：）

Answer 1

您可以按照以下方式执行此操作：

foreach($jsonobj->d->results as $result) {
    foreach($result->Web as $value) {
        echo $value->Title;
        // and the same for the other properties
    }
}

顺便说一句：您应该使用工具来格式化您的json字符串。通过这种方式，可以更清楚地了解json数据的样子。

Answer 2

results包含一个数组，所以你需要这样的东西：

foreach($jsonobj->d->results[0]->Web as $value)
{
    echo 'Title: ' . $value->Title . '<br /><br />';
    echo 'Description: ' . $value->Description . '<br /><br />';
    echo 'Url: ' . $value->Url . '<br /><br /><br />';
}

Answer 3

首先使用print_r方法，这样你就可以看到对象是怎样的，因此你可以确定从哪里开始循环。

echo '<pre>';
print_r($jsonobj);

然后将类型更改为数组，如$ array =（array）$ jsonobj;所以你可以将它用于array_shift函数（你可以使用这个函数调整你的数组）
