mysqlinsert PHP+MySQL50 Chinese garbled solution

I recently studied Apache2+PHP4.4.1+MySQL5.0, and the Chinese characters displayed on the page were all "???.....". I found a lot of information on the Internet and found a simple solution!
Database connection PHP script content:
config.inc.php
//Configure mysql database connection parameters
$db = mysql_connect("localhost", "user","password");
mysql_select_db(" message",$db);
//Add the following line before executing the sql statement
mysql_query("SET NAMES 'gb2312'",$db);
?>

The above introduces the solution to mysqlinsert PHP+MySQL50 Chinese garbled code, including the content of mysqlinsert. I hope it will be helpful to friends who are interested in PHP tutorials.
