Solution to the problem of Chinese garbled characters inserted into mysql database by php

Today I reinstalled the system and reinstalled the PHP operating environment. I didn’t pay too much attention to it. I thought Write something to review and review... When I used INSERT INTO to add data to the data table, I found that as long as the data was in Chinese, it was displayed in garbled characters, so I specified the language in the web page as gbk and found that it still didn't work. On the Internet After searching for a long time, I made a summary:

1.php page should be saved in UTF-8 encoding format.

2.php must use UTF8 when submitting data.

3. When creating a table in MYSQL, use ENGINE=MyISAM DEFAULT CHARSET=utf8;

Example (because I am too lazy to write, this example on the Internet feels quite clear):

Build table:

Create TABLE `net_city` (
`cityid` smallint(4) NOT NULL auto_increment,
`cityname` varchar(80) NOT NULL default '',
`provinceid` smallint(2) NOT NULL default '0',
`inarea` varchar(5000) NOT NULL default '',
`outarea` varchar(5000) NOT NULL default '',
`tel` varchar(400) NOT NULL default '',
PRIMARY KEY (`cityid`)
) ENGINE=MyISAM DEFAULT CHARSET=utf8;

Code in PHP:

$conn=mysql_connect("localhost", "用户名", "密码");
mysql_query("set names 'utf8'",$conn);
mysql_select_db("数据名",$conn);
$exec="insert into net_city (cityname,inarea,outarea,tel) values ('".$link_cityname."','".$link_inarea."','".$link_outarea."','".$link_tel."')";
$result=mysql_query($exec,$conn);
if($result){
       echo "1";
     }else{
        echo "0";
     }
mysql_close($conn);

Later I tried to use gbk for all, and it was ok~
