首先，我对 PHP 非常陌生，所以我仍在尝试。我的问题是：我试图在 PHP 中回显 Bing API 结果。

这是一个 JSON 结果示例，我从中获得

$jsonobj = json_decode($response);

（回复是我从 Bing 得到的，所以我只是粘贴了下面的回复 - 只需添加此信息，以防您想知道我从哪里得到$jsonobj = json_decode($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，我知道我可以使用以下命令来回显 WebTotal：

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

但是，我不知道如何回显实际结果，例如Title,Description和Url.

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 Web 添加到foreach遗嘱中可能会呼应正确的价值观，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：

标题：PHP：超文本预处理器

说明：什么是PHP？PHP 是一种广泛使用的通用脚本语言，特别适用于 Web 开发，并且可以嵌入到 HTML 中。

网址：http://www.php.net/

然后，其他两个结果。

太感谢了 ：）

您可以按如下方式执行此操作：

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：你应该使用一个工具来格式化你的 json 字符串。这样会更清楚 json 数据的样子。

首先使用 print_r 方法，这样您就可以看到对象的外观，从而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）
