PHP中json中文乱码问题解决

问题:

众所周知使用json_encode可以方便快捷地将对象进行json编码,但是如果对象的属性中存在着中文,问题也就随之而来了。

json_encode会将中文转换为unicode编码,例如:'我'经过json_encode处理后变为'\\u6211',最终的json中中文部分被替换为unicode编码。我们要解决的就是将对象转换为json并保证对象内部的中文在json中仍然是以正常的中文出现,现在看来只使用json_encode是不能达到目的的。

解决方法:先将类中的中文字段进行url编码(urlencode),然后再对对象进行json编码(jsonencode),最后url解码(urldecode)json,即最终的json,里面的中文依旧是那个中文,完成我们想要的效果

<meta charset="utf-8">
<?php
//1.将数组、对象转为json格式(数组、对象都不包含中午)
$arr=array(&#39;a&#39;=>&#39;a&#39;,&#39;b&#39;=>&#39;b&#39;); //string &#39;{"a":"a","b":"b"}&#39; (length=17)
var_dump(json_encode($arr));
class Person{
private $money=0;
public $name=null;
protected $lover=null;
public function __construct($name,$money,$lover){
$this->name=$name;
$this->money=$money;
$this->lover=$lover;
}
public function getName(){
return $this->name;
}
protected function getLover(){
return $this->love;
}
private function getMoney(){
$this->money;
}
}
$zhangsan=new Person(&#39;zhagnsan&#39;,&#39;9999999&#39;,&#39;beautiful grils&#39;);
//只会将类中public属性转为json格式
var_dump(json_encode($zhangsan)); //string &#39;{"name":"zhangsan"}&#39; (length=19)
//对于数组或是对象包含中文,json_encode会将中文转换为unicode编码,
//解决方法:先将类或是数组中的中文字段进行url编码(urlencode),然后再对对象或是数组进行json编码(jsonencode),最后url解码(urldecode)json,即最终的json
$arr=array(&#39;ename&#39;=>&#39;dqs&#39;,&#39;cname&#39;=>&#39;你猜啊&#39;);
var_dump(json_encode($arr)); //中文,出现乱码,string &#39;{"ename":"dqs","cname":"\\u4f60\\u731c\\u554a"}&#39; (length=44)
$arr[&#39;cname&#39;]=urlencode($arr[&#39;cname&#39;]);
$arr_json=urldecode(json_encode($arr));
var_dump($arr_json); //string &#39;{"ename":"dqs","cname":"你猜啊"}&#39; (length=35)
//3.补充知识,查看字符编码方式以及转码
$name="dsq,你好啊";
//iconv_get_encoding()获取当前页面的编码信息
var_dump(mb_detect_encoding($name)); //UTF-8
$name=iconv("UTF-8","GB2312//IGNORE",$name);  
var_dump(mb_detect_encoding($name)); //UTF-8
//思考,为什么将utf-8编码转为gb2312后还是utf-8呢?
查看字符串编码mb_detect_encoding
//echo mb_detect_encoding($arr[&#39;cname&#39;]);
//$newData=iconv("GB2312","UTF-8//IGNORE",$data);
Copy after login

Explain JSON Web Tokens (JWT) and their use case in PHP APIs. Explain JSON Web Tokens (JWT) and their use case in PHP APIs. Apr 05, 2025 am 12:04 AM

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,
