如何从这个MASSIVE json对象中获取分数？

标签： php function

我想要$ result ['得分']但是，尽管尝试了$ result-＆gt;得分，$ result [0]和$ result [stdClass] ['得分']，但它永远不会返回true;非常感谢所有帮助。

Object(stdClass)#1 (9) { ["kind"]=> string(22) "pagespeedonline#result" ["id"]=> string(34) "https://www.google.com/?gws_rd=ssl" ["responseCode"]=> int(200) ["title"]=> string(6) "Google" ["score"]=> int(92) ["pageStats"]=> object(stdClass)#2 (9) { ["numberResources"]=> int(13) ["numberHosts"]=> int(5) ["totalRequestBytes"]=> string(4) "2295" ["numberStaticResources"]=> int(8) ["htmlResponseBytes"]=> string(6) "190230" ["imageResponseBytes"]=> string(5) "45452" ["javascriptResponseBytes"]=> string(6) "780563" ["otherResponseBytes"]=> string(4) "1867" ["numberJsResources"]=> int(4) } ["formattedResults"]=> object(stdClass)#3 (2) { ["locale"]=> string(5) "en_US" ["ruleResults"]=> object(stdClass)#4 (10) { ["AvoidLandingPageRedirects"]=> object(stdClass)#5 (3) { ["localizedRuleName"]=> string(28) "Avoid landing page redirects" ["ruleImpact"]=> float(7) ["urlBlocks"]=> array(2) { [0]=> object(stdClass)#6 (1) { ["header"]=> object(stdClass)#7 (2) { ["format"]=> string(96) "Your page has $1 redirects. Redirects introduce additional delays before the page can be loaded." ["args"]=> array(1) { [0]=> object(stdClass)#8 (2) { ["type"]=> string(11) "INT_LITERAL" ["value"]=> string(1) "2" } } } }

Here is a copy格式化对象的粘贴框

会这样做：

根据请求，这是我将回声更改为echo "Score Speed is: ". print_r(json_decode($result[0]->score, true)) . "<br/>";

所得到的输出

（还有echo "Score Speed is: ". print_r(json_decode($result[0]->score)) . "<br/>";）

得分速度为：1

抱歉，这不是更具描述性的。

最终编辑：谢谢大家的帮助......这种组合产生了我的数据：

    $formatted = json_decode($results, JSON_PRETTY_PRINT);

//我使用True而不是JSON_PRETTY_PRINT

来使用旧版本 
    echo "formatted data: " . $formatted[0]->score . "<br/>";

//最终无法正常工作

    echo "2nd try: ". $formatted['score'];

//这个可以工作。

...

... 

      //This is the [original piece of code I used as a reference point is here][2]
    echo '<pre>';  
    print_r(json_decode($results['score'],true));   
    echo '</pre>';

1 个答案:

答案 0 :(得分：2)

你这是错误的方式。您正在尝试解码已解码的值。

只需尝试echo'输出值：

echo $result[0]->score;

这是最后一步。我觉得在此之前的每一步都是错误的 - 导致您无法打印出预期值的问题。

您应该执行以下过程：

$data = FETCH_THE_JSON_FROM_DATA_SOURCE();
$json = json_decode($data);
// now we find data
echo $json[0]->score;

注意：上面的代码是伪代码，您需要适当填写您的部分。

如果我们看不到原始json数据，我们无法告诉您如何获取它。所以，帮助我们帮助你。
