我如何使用它，以便我可以从阵列中挑选推文，例如。 $tweets[2];我尝试了json_decode，但没有运气。

2 个答案:

答案 0 :(得分：1)

您可以尝试将第二个参数传递给json_decode，它会将所有json数据转储为关联数组 link

答案 1 :(得分：0)

如果您尝试将JSON输出存储在字符串中，则由于其中未转义的单引号，它将失败。

例如，JSON输出中包含以下文本：

"text": "\"I fear we'll get ourselves involved in another endless conflict\" 
            //------^

因此，如果您尝试将JSON分配给字符串，它将失败并产生解析错误，因为它中包含单引号。因为您的JSON包含双引号，所以您也不能使用它。

要告诉PHP忽略引号并将其解释为字符串，您可以使用heredoc语法，如下所示：

$string = <<<JSON
... json ...
JSON;

$json = json_decode($string);
echo $json[0]->text."\n"; 
echo $json[1]->text."\n";

注意：如果您想要获得关联数组，可以将json_decode()的第二个参数传递为TRUE。

Working demo!
