PHP json_decode return error code 4
提问by Patrick Ng
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:
我之前也问过同样的问题。我想解码来自：http: //pad.skyozora.com/data/pets.json的 json 。下面是我之前使用的代码：
<?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
?>
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.
从最后一个答案我知道json返回中有UTF8 DOM。我尝试了类似问题的答案：json_decode 在 webservice call 后返回 NULL，但所有的答案都不适合我。
And after do more research I found a way that works:
在做了更多的研究之后，我找到了一种有效的方法：
<?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());
?>
This successfully decode the json into array. However all Chinese and Japanese character string were removed too. Any ideas?
这成功地将json解码为数组。然而，所有的中文和日文字符串也被删除了。有任何想法吗？

编辑：
I used http://jsonlint.com/to decode the json from http://pad.skyozora.com/data/pets.json. It stops at here:
我使用http://jsonlint.com/解码来自http://pad.skyozora.com/data/pets.json的 json 。它停在这里：

Expecting 'STRING', 'NUMBER', 'NULL', 'TRUE', 'FALSE', '{', '['
But I couldn't see any problem with this part of json.
但是我看不出这部分 json 有任何问题。

The return error code 4 is due to a JSON_ERROR_SYNTAXyou must try to fix your json.
