Question

对不起，我很擅长学习PHP。我试图找到这个话题，但没有得到答案，希望有人可以帮助我。

我尝试从Rottentomatoes的API Json中显示，如果Rottentomatoes Json输出：

 {"total":109,"reviews":[{"critic":"Andrea Chase","date":"2014-07-25","original_score":"2/5","freshness":"rotten","publication":"Killer Movie Reviews","quote":"succeeds only as an advertisement for the tablet mentioned every dozen words or so, and that forms the McGuffin chased with sadly ineffectual diligence by Segal and Diaz.","links":{"review":"hxxp://www.killermoviereviews.com/main.php?nextlink=display&dId=1818&subLinks="}}]

我如何在php中显示“Andrea Chase”值？

现在我怀疑从“总”值显示“109”，这是我的代码

e$url1   = 'hxxp://my-url-api-link';
$data = json_decode(file_get_contents($url1));
$total = $data->total;

echo $total;

为了这个问题，我将你的JSON放入变量：

$json = '{"total":109,"reviews":[{"critic":"Andrea Chase","date":"2014-07-25","original_score":"2/5","freshness":"rotten","publication":"Killer Movie Reviews","quote":"succeeds only as an advertisement for the tablet mentioned every dozen words or so, and that forms the McGuffin chased with sadly ineffectual diligence by Segal and Diaz.","links":{"review":"hxxp://www.killermoviereviews.com/main.php?nextlink=display&dId=1818&subLinks="}}]}';

现在，如果你这样做：

echo "<pre>";
$data = json_decode($json);
print_r($data);

您将获得持有Standard Object的{{1}} PHP：

JSON

根据此结构，您可以通过以下方式获取stdClass Object ( [total] => 109 [reviews] => Array ( [0] => stdClass Object ( [critic] => Andrea Chase [date] => 2014-07-25 [original_score] => 2/5 [freshness] => rotten [publication] => Killer Movie Reviews [quote] => succeeds only as an advertisement for the tablet mentioned every dozen words or so, and that forms the McGuffin chased with sadly ineffectual diligence by Segal and Diaz. [links] => stdClass Object ( [review] => hxxp://www.killermoviereviews.com/main.php?nextlink=display&dId=1818&subLinks= ) ) ) )：

Andrea Chase

这是如何工作的：

data是一个带有名为review的属性的对象 - 所以echo $data->reviews[0]->critic;

现在评论是一个数组，我们需要它的第一个索引 - 所以$data->reviews

第一个索引又是一个名为critic的属性的对象。所以基于前面的解释：$data->reviews[0]

要记住的基本想法是$data->reviews[0]->critic被访问为Array indexes等。 $array[0], $array[1]访问Object properties，$object->property1等。

如何从Rottentomatoes显示数组。？
