mb_convert_encoding function is PHP's internal multi-byte string encoding conversion function. It can support almost all encodings when needed. PHP >= 4.0.6, 5 versions supported.

Get reg.php?gh=XX directly;

//Union login parameters

$gonghui = $_GET['gh'];

The obtained $gonghui is gb2312 encoded and output to the utf-8 webpage to display garbled characters

Changed to

// Union login parameters
$gonghui = $_GET['gh'];
$gonghui = mb_convert_encoding($gonghui, "UTF-8", "gb2312");

In this way, all character sets other than the first 128 characters (display characters) are represented by NCR (Numeric character reference, such as "Chinese characters" will be converted into "Chinese characters"). This encoding can be used on the page in any encoding environment. normal display.

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

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');

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.
