php中json_encode中文字符乱码解决办法
大致的解决办法是保证在使用JSON处理的时候字符是以UTF8编码的。具体我们可以把数据库编码和页面编码都改为UTF8。当然喜欢用gbk编码的话,可以在进行JSON处理前,把字符转为UTF8形式
一、json_encode()
这个是一个对变量进行 JSON 编码常用的函数,但是当文本的格式不是utf-8时,中文的转码会出现一些问题,比如文本为gb2312的时候
示例
代码如下 | 复制代码 |
$jsonText = array ( |
解决办法
代码如下 | 复制代码 |
foreach ($jsonText as $key=>$value) |
用上面的代码js会报错 说编码不符合标准
原因是因为js 中decodeURI 仅仅支持utf8 转码。所以 ,PHP json_encode函数的代码应该为下面的代码
代码如下 | 复制代码 |
foreach ($jsonText as $key=>$value) 查看输出结果为: {“name”:”u4e2du6587u5b57u7b26u4e32″,”value”:”test”} |
可见即使用UTF8编码的字符,使用json_encode也出现了中文乱码。解决办法是在使用json_encode之前把字符用函数urlencode()处理一下,然后再json_encode,输出结果的时候在用函数urldecode()转回来。具体如下:
代码如下 | 复制代码 |
$testJSON=array('name'=>'中文字符串','value'=>'test'); |
查看输出结果为:
代码如下 | 复制代码 |
{“name”:”中文字符串”,”value”:”test”} |
到此,成功地输出了中文字符。随意使用json_encode吧。这样子在PHP后台输出的JSON字符串在前台javascript中Ajax接收后eval出来也不会出现中文乱码,因为js在处理JSON格式数据是也是以UTF8的形式进行的,与PHP类似,故接收PHP页面的JSON字符串不会出现问题。

JWT is an open standard based on JSON, used to securely transmit information between parties, mainly for identity authentication and information exchange. 1. JWT consists of three parts: Header, Payload and Signature. 2. The working principle of JWT includes three steps: generating JWT, verifying JWT and parsing Payload. 3. When using JWT for authentication in PHP, JWT can be generated and verified, and user role and permission information can be included in advanced usage. 4. Common errors include signature verification failure, token expiration, and payload oversized. Debugging skills include using debugging tools and logging. 5. Performance optimization and best practices include using appropriate signature algorithms, setting validity periods reasonably,
