php地址栏传中文$_GET下来后乱码,urlencode和urldecode用法详解
url编码
语法: string urlencode(string str);
返回值: 字符串
函数种类: 编码处理
例如:

复制代码 代码如下:

$ChineseName="我的名字,是中文的哦";
$EncodeStr=urlencode($ChineseName);
echo "我的名字";
?>

url解码
还原 URL 编码字符串。
语法: string urldecode(string str);
返回值: 字符串
函数种类: 编码处理
例如:
对前面传过来的中文进行处理显示
复制代码 代码如下:

$DecodeStr=urldecode($_GET['name']);//你可能不用解码都可以,因为浏览器会自动帮你解码
echo $DecodeStr;
?>

关于php用get方法从url上获得的中文乱码问题

使用$gonghui = iconv("gb2312","UTF-8",$gonghui);另一方法代码
/**
* 多字节字符串编码转换函数
*
* @param string str 需要进行编码转换的字符串
* @param string to_encoding 指定转换为某种编码,如:gb2312、gbk、utf-8等
* @param mixed from_encoding 混合指定原来字串的编码,如:同时指定 JIS, eucjp-win, sjis-win 混合编码
* @return string
string mb_convert_encoding ( string str, string to_encoding [, mixed from_encoding] )
**/
mb_convert_encoding 函数为php内部多字节字符串编码转换函数,可以在有需要的使用场合,几乎支持所有编码。PHP  >= 4.0.6、 5 版本支持。

直接获取 reg.php?gh=某某;

 //工会登入参

$gonghui = $_GET['gh'];

获得的$gonghui 为gb2312编码 输出到utf-8网页上显示乱码

改成

 //工会登入参数
 $gonghui = $_GET['gh'];
 $gonghui = mb_convert_encoding($gonghui, "UTF-8", "gb2312");

 就显示正常了

对整个页面进行转换

该方法适用所有编码环境。这样把前128个字符以外(显示字符)的字符集都用   NCR(Numeric character reference,如“汉字”将转换成“汉字”这种形式)来表示,这样的编码在任意编码环境下页面都能正 常显示。

在php文件的头部加上下面三行代码:

复制代码 代码如下:

mb_internal_encoding("gb2312");  // 这里的gb2312是你网站原来的编码    
mb_http_output("HTML-ENTITIES");    
ob_start('mb_output_handler'); 

使用mb_convert_encoding 函数需启用PHP 的mbstring (multi-byte string)扩展。

如果没有没有开启php的mbstring扩展,则需要做如下设置,让php支持该扩展。

1、windows 服务器环境
编辑 php.ini 文件,将; extension=php_mbstring.dll 前面的 ; 去掉,重启网页服务器。

2、Linux服务器环境
在编译配置时加入 --enable-mbstring=cn 编译参数,再进行PHP的编译安装。

其它网友的第三个参考方法:
//方法一 urldecode
$url = 'aaa.php?region='.urldecode("四川省");
aaa

//方法二base64_encode


$test="四川省";
$test1=base64_encode($test);
echo 'aaa ';
?>

另一页面使用base64_decode解开

base64_decode($region);

//方法三让服务器支持中文

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,
