PHP json_decode返回错误代码4 [英] PHP json_decode return error code 4
问题描述
我以前曾问过同样的问题。我想从以下位置解码json: http://pad.skyozora.com/data/pets。 json 。下面是我以前使用的代码:
I had previously asked the same question. I would like to decode the json from: http://pad.skyozora.com/data/pets.json. Below is the code I used previously:
<?php
$html=file_get_contents("http://pad.skyozora.com/data/pets.json");
var_dump(json_decode($html,true)); //return null
var_dump(json_last_error()); // return 4
?>
从最后一个答案中我知道json返回中存在UTF8 DOM。我尝试了一个类似问题的答案: json_decode在网络服务调用后返回NULL ,但所有答案对我都不起作用。
From the last answer I know there is UTF8 DOM in the json return. I tried the answer from a similar question: json_decode returns NULL after webservice call, but all of the answers not work for me.
经过更多研究,我发现了一种可行的方法:
And after do more research I found a way that works:
<?php
$html=file_get_contents("http://pad.skyozora.com/data/pets.json");
$html=preg_replace('/[\x00-\x1F\x80-\xFF]/', '', $html);
var_dump(json_decode($html, true));
var_dump(json_last_error());
?>
这成功地将json解码为数组。但是,所有的中文和日文字符串也被删除。有任何想法吗?
This successfully decode the json into array. However all Chinese and Japanese character string were removed too. Any ideas?
已编辑
我使用了 http://jsonlint.com/ 解码来自 http://pad.skyozora.com/data/pets.json 。它停在这里:

并给我错误:

Expecting 'STRING', 'NUMBER', 'NULL', 'TRUE', 'FALSE', '{', '['
但是我看不到json的这一部分有任何问题。
But I couldn't see any problem with this part of json.
返回错误代码4是由于 JSON_ERROR_SYNTAX
引起的,您必须尝试修复json。

you must try to fix your json.
如果您在浏览器中转到URL,您会看到以下消息:
