Get reg.php?gh=XX directly;

 //工会登入参
$gonghui = $_GET['gh'];

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

The display will be normal

Convert the entire page

This method is applicable to all coding environments. 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:

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');

$url = 'aaa.php?region='.urldecode("四川省");
<a href="<?php echo $url;?>">aaa </a>

<?
$test="四川省";
$test1=base64_encode($test);
echo &#39;<a href="www.jb51.net?region=$test1">aaa </a>&#39;;
?>

Use base64_decode to unlock another page

base64_decode($region);
