* Multi-byte string encoding conversion function
*
* @ Param string str the string to be encoded and converted
* @ Param string to_encoding specifies the conversion to a certain encoding, such as gb2312, gbk, and UTF-8.
* @ Param mixed from_encoding: specify both the encoding of the original string, for example, JIS, eucjp-win, and sjis-win.

String mb_convert_encoding (string str, string to_encoding [, mixed from_encoding])

The mb_convert_encoding function is a multi-byte character string conversion function in php. it can be used as needed and supports almost all encoding. PHP> = 4.0.6 and 5.

Get reg. php directly? Gh = xx;

// Trade union login parameters

$ Gonghui = $ _ GET ['GH'];

The obtained $ gonghui is gb2312 encoded and output to the UTF-8 webpage with garbled characters.

Change

// Union login parameters
$ Gonghui = $ _ GET ['GH'];
$ Gonghui = mb_convert_encoding ($ gonghui, "UTF-8", "gb2312 ");

It is displayed as normal.

If the php mbstring extension is not enabled, you need to make the following settings to allow php to support the extension.

1. windows Server environment
Edit the php. ini file, and replace the file before extension = php_mbstring.dll. remove the file and restart the web server.

2. Linux server environment
Add the -- enable-mbstring = cn compilation parameter during compilation configuration, and then compile and install PHP.

// Method 1 urldecode
$ Url = 'AAA. php? Region = '. urldecode ("Sichuan province ");
"> Aaa

// Method 2: base64_encode

$ Test = "Sichuan province ";
$ Test1 = base64_encode ($ test );
Echo 'AAA ';
?>

Use base64_decode to unlock the other page

Base64_decode ($ region );

// Method 3 enable the server to support Chinese characters
