如何在 php 中对原始 json 字符串进行编码

Question

我有JSON，它已保存在我网站的文本框中，并保存到下面的数据库中。

{"@type":"GOOOGLE.COM","@id":"GOOGLE","url":"GOOGLE","inLanguage":"en-US","name":"dfghjk | Bloomberg Professional Services","isPartOf":{"@id":"GOOGLE,"datePublished":"2020-02-11T21:51:45+00:00","dateModified":"2020-02-11T21:51:45+00:00"}]}

我想将其转换为PHP中的正确外观，如下所示：

{"@type":"GOOOGLE.COM","@id":"GOOGLE","url":"GOOGLE","inLanguage":"en-US","name":"dfghjk | Bloomberg Professional Services","isPartOf":{"@id":"GOOGLE,"datePublished":"2020-02-11T21:51:45+00:00","dateModified":"2020-02-11T21:51:45+00:00"}]}

我试着做了一个json_encode但它不起作用。如何将带有所有这些转义引号等的字符串转换为PHP中的普通json字符串？

我试过这样：

  $str = "{"@type":"GOOOGLE.COM","@id":"GOOGLE","url":"GOOGLE","inLanguage":"en-US","name":"dfghjk | Bloomberg Professional Services","isPartOf":{"@id":"GOOGLE,"datePublished":"2020-02-11T21:51:45+00:00","dateModified":"2020-02-11T21:51:45+00:00"}]}"

  $data = json_encode($str, true);  

  return $data;

您需要将 HTML 实体解码回字符：https://www.php.net/manual/en/function.htmlspecialchars-decode.php  $json = htmlspecialchars_decode($str, true);  // valid json string  $data = json_decode($json); // convert json to php data structure  return $data;
