请教个json解析问题

Question

我有几个json串
{"clusterno":167145108,"clustertype":1,"subid":"0","newperson":"欢迎【.dazuo.昵称.dayou.】来到群【.dazuo.群名.dayou.】.enter.信息：.enter..dazuo.信息.dayou..enter..dazuo.退群次数.dayou..enter.请改群名片：帮派名┃职位 或者 帮派名┃职位┃昵称.enter.名称不符.douhao.不改名者送去夏威夷...enter..jhao..jhao..jhao..jhao..jhao..jhao..jhao..jhao..jhao..jhao..jhao..jhao..jhao..jhao..jhao..jhao..jhao..jhao..jhao..jhao..jhao..jhao..jhao..jhao..jhao..jhao..jhao..jhao..jhao..jhao..jhao..jhao..jhao..jhao..jhao..jhao..jhao..jhao..jhao..jhao..jhao..jhao..jhao..jhao..jhao..jhao..jhao..jhao..jhao..jhao..jhao..jhao..jhao..jhao..jhao..jhao..jhao..jhao..jhao..jhao..jhao..jhao..jhao..jhao..jhao..jhao..jhao..jhao..jhao..jhao..jhao..jhao..jhao..jhao..jhao..jhao..jhao..jhao..enter.\.douhao.\是机器人.douhao.请直接无视忽略.","removeperson":"","expdatetime":"2021-10-18 23:50:42","userid":"1","username":"admin","updatecode":"7ECEDB4E1037476EAAF5FB5E8340AAEE"}用json_decode解析会出现是null的.我测试了 一下,是newperson这个接点太长导致的,有没有什么方法可以解决这个问题

Answer 1

反斜杠转义，转换编码
<?php
$json='{"clusterno":167145108,"clustertype":1,"subid":"0","newperson":"欢迎【.dazuo.昵称.dayou.】来到群【.dazuo.群名.dayou.】.enter.信息：.enter..dazuo.信息.dayou..enter..dazuo.退群次数.dayou..enter.请改群名片：帮派名┃职位 或者 帮派名┃职位┃昵称.enter.名称不符.douhao.不改名者送去夏威夷...enter..jhao..jhao..jhao..jhao..jhao..jhao..jhao..jhao..jhao..jhao..jhao..jhao..jhao..jhao..jhao..jhao..jhao..jhao..jhao..jhao..jhao..jhao..jhao..jhao..jhao..jhao..jhao..jhao..jhao..jhao..jhao..jhao..jhao..jhao..jhao..jhao..jhao..jhao..jhao..jhao..jhao..jhao..jhao..jhao..jhao..jhao..jhao..jhao..jhao..jhao..jhao..jhao..jhao..jhao..jhao..jhao..jhao..jhao..jhao..jhao..jhao..jhao..jhao..jhao..jhao..jhao..jhao..jhao..jhao..jhao..jhao..jhao..jhao..jhao..jhao..jhao..jhao..jhao..enter.\.douhao.\是机器人.douhao.请直接无视忽略.","removeperson":"","expdatetime":"2021-10-18 23:50:42","userid":"1","username":"admin","updatecode":"7ECEDB4E1037476EAAF5FB5E8340AAEE"}';
$json=addcslashes($json,'\\');
var_dump(json_decode(iconv('GBK','UTF-8',$json),true));
?>

Answer 2

utf-8编码文件就不需要再  iconv了.参考楼上的.

Answer 3

不好意思了..自己搞错了是 dfsockopen函数的有返回截取的..我设置了600...超了json格式就错了哈.谢谢各位
