Settings for the database:

Look in the my.ini file for:

[mysql]

Default-character-set = utf8

[mysqld]

Default-character-set = utf8

Init_connect = 'SET NAMES utf8'

All set to utf8

Save, restart the mysql service

two。 Mysql_query ("set names' utf8'") when dealing with data; note: utf8, not utf-8

3.PHP file default encoding is ANSI, need to be converted to UTF-8, as for how to convert editplus has such a function, "Save as" when there is a choice of encoding UTF-8, note: can not choose: UTF-8 + BOM, if you choose this, you will have problems when dealing with session, so be sure to pay attention. Some people develop in eclipse,Myeclipse,ZendStudio. The default in eclipse is ISO-8859-1. You need to open the preferences window in "window"-> "preferences", in "General"-> "Workspace" on the left, and set the default encoding to utf-8 in "text File Encoding".

In addition (one missing point), in your program, you need to know that there may also be coding problems in the transmission of data, but you do not know what kind of coding is used in the transmitted data. The method is provided in PHP to deal with it. Here is a simple method written by yourself, which you can refer to.

The copy code is as follows:

/ / Transcoding

Function display_fileencoding ($filename)

{

If (extension_loaded ("mbstring"))

{

$code=mb_detect_encoding ($filename); / / detect string encoding

$filename=mb_convert_encoding ($filename, "UTF-8", $code); / / convert the encoding $code to utf-8 encoding

Return $filename

}

Die ("Please check that the system is properly installed and configured mbstring")

}

Make sure mbstring is enabled in your php.ini
