[英]PHP json_decode return error code 4
I had previously asked the same question. 我之前曾问过同样的问题。 I would like to decode the json from: http://pad.skyozora.com/data/pets.json . 我想解读json: http : //pad.skyozora.com/data/pets.json 。 Below is the code I used previously: 以下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. 从最后一个答案我知道json返回中有UTF8 DOM。 I tried the answer from a similar question: json_decode returns NULL after webservice call , but all of the answers not work for me. 我尝试了类似问题的答案: json_decode在webservice调用后返回NULL ,但所有答案对我都不起作用。
And after do more research I found a way that works: 经过更多的研究后,我发现了一种有效的方法:
<?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. 这成功地将json解码为数组。 However all Chinese and Japanese character string were removed too. 但是所有中文和日文字符串也被删除了。 Any ideas? 有任何想法吗?
Edited: 编辑:
I used http://jsonlint.com/ to decode the json from http://pad.skyozora.com/data/pets.json . 我使用http://jsonlint.com/从http://pad.skyozora.com/data/pets.json解码json。 It stops at here: 它停在这里:

Expecting 'STRING', 'NUMBER', 'NULL', 'TRUE', 'FALSE', '{', '['
But I couldn't see any problem with this part of json. 但我看不出这部分json有什么问题。
The return error code 4 is due to a JSON_ERROR_SYNTAX
you must try to fix your json. 返回错误代码4是由JSON_ERROR_SYNTAX
引起的,你必须尝试修复你的json。
