Detailed explanation and examples of php outputting json and displaying Chinese characters in json
php 输出json及显示json中的中文汉字
在php中,我们经常需要将数组输出json,只需要使用json_encode函数处理一下数组即可,但有的时候数组里面有中文,使用json_encode函数处理后中文字符被编码成了Unicode,如何才能在json中显示中文呢?请看下文。
首先介绍一下php输出json格式:
一种最简单的用法,就是把数组直接输出为json,如下:
<?php $arr = array('p1'=>'ni"hao','p2'=>2,'ch'=>'码农你好!'); $json = json_encode($arr); echo $json; ?>
输出的结果为:
{"p1":"ni\"hao","p2":2,"ch":"\u7801\u519c\u4f60\u597d\uff01"}
这里要注意:
双引号在json中会被自动编码为\",这个很好理解,js中字符串中是不允许出来单引号、双引号和反斜杠的。
中文字符被编码成了Unicode
如果是写接口,那直接这样输出就够了,中文无需去做处理。等到了客户端,再去把Unicode的中文转成汉字即可。但如果要在服务器端直接输出汉字出来,那我们可以做如下处理。
<?php $arr = array('p1'=>'nihao','p2'=>2,'ch'=>'码农你好!'); $json = json_encode($arr); echo decodeUnicode($json); function decodeUnicode($str){ return preg_replace_callback('/\\\\u([0-9a-f]{4})/i', create_function( '$matches', 'return mb_convert_encoding(pack("H*", $matches[1]), "UTF-8", "UCS-2BE");' ), $str); } ?>
输出:
{"p1":"ni\"hao","p2":2,"ch":"码农你好!"}
这个操作很简单,其实就是把输出结果匹配一下,把Unicode还原成了汉字。

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,

The application of SOLID principle in PHP development includes: 1. Single responsibility principle (SRP): Each class is responsible for only one function. 2. Open and close principle (OCP): Changes are achieved through extension rather than modification. 3. Lisch's Substitution Principle (LSP): Subclasses can replace base classes without affecting program accuracy. 4. Interface isolation principle (ISP): Use fine-grained interfaces to avoid dependencies and unused methods. 5. Dependency inversion principle (DIP): High and low-level modules rely on abstraction and are implemented through dependency injection.
