$gonghui = iconv("gb2312","UTF-8",$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 stringstring mb_convert_encoding ( string str, string to_encoding [, mixed from_encoding] )
**/

mb_convert_encoding
The function is PHP's internal multi-byte string encoding conversion function. It can support almost all encodings when needed.
Get reg.php directly? gh=XX;

//工会登入参
$gonghui = $_GET['gh'];

obtained

$gonghui

is gb2312 encoded and output to the utf-8 web page to display garbled characters changed to

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

The display is normal

Convert the entire page

This method is applicable to all encoding environments. In this way, all character sets other than the first 128 characters (display characters) use NCR (Numeric character reference, such as "Chinese characters" will be converted into the form of "Chinese characters"), and this encoding can display the page normally in any encoding environment.

Add the following three lines of code to the head of the php file:

The code is as follows:

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');

Using the

mb_convert_encoding

function requires enabling PHP’s mbstring (multi-byte string) extension. If you do not enable php’s mbstring extension, you need to make the following settings to allow PHP to support the extension.

1. Windows server environment

Edit the php.ini file, remove the ; in front of extension=php_mbstring.dll, and restart the web server.

2. Linux server environment

Add the --enable-mbstring=cn compilation parameter when compiling the configuration, and then compile and install PHP.
