php中GBK/GB2312页面使用json_decode()中文丢失了解决方法

decode gbk json php lost Chinese use exist method solve page

在php中json_decode()函数可以把数组与json格式的数据相互转换,但json_decode()函数只支持UTF-8与ASCII编码,如果是gkb就会出问题,下面我们来看看问题分析与解决办法。

好像用json_decode()将数组/对象 序列化为JSON字符串的时候基本上只支持 UTF-8/ASCII编码。而我们有的站采用了GBK/GB2312编码,这个时候,直接使用json_encode/json_decode的时候就可能会出问题了。

 代码如下 复制代码

$json = '{"a":"中国人人"}';
var_dump(json_decode($json));
?>

结果

{"text":null,"status":1}

比如转含有中文的字符字变成空(null),但有时候我们又必须得用gb编码而又要用到json_decode()转换的时候呢?什么办呢?自己昨晚写了一个不用数据库的一个添加音乐的小后台。也就是用php添加音乐,然后生成xml菜单。不用数据库那也得用一个方式来保存数据了。保存成文本的数据再可以直接拿出来用的,我想是把数组json_decode()用它转成json格式,用的时候再拿出来用它json_encode转回数组就可以了(可能最近弄js被json影响了,好像把数组序列化还有更好的方法,比如用:serialize()和unserialize()),呵呵,转正题。既然json_decode()在gb编码上转不了中文,那么我们可以先把中文转成英文编码的形式。那可以使用这个urlencode()转一下编码,再做json_decode()转换。使用的时候,再用urldecode()转成中文就可以了

 代码如下 复制代码

/*
    字符串GBK转码为UTF-8,数字转换为数字。
*/
function ct2($s){
    if(is_numeric($s)) {
        return intval($s);
    } else {
        return iconv("GBK","UTF-8",$s);
    }
}
/*
    批量处理gbk->utf-8
*/
function icon_to_utf8($s) {
  if(is_array($s)) {
    foreach($s as $key => $val) {
      $s[$key] = icon_to_utf8($val);
    }
  } else {
      $s = ct2($s);
  }
  return $s;
}
echo json_encode(icon_to_utf8("厦门"));

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,
