An example solution to the Chinese garbled code when php writes to mysql

The solution to the Chinese garbled code when php writes to mysql is: after establishing the database connection, change the encoding method of the connection for Chinese.

The code is as follows:

$linkID=@mysql_connect("localhost","root","admin"); if(!$linkID) { echo "数据库连接失败！"; } echo "数据库连接成功！"; mysql_query("SET character_set_connection = GBK",$linkID);//将连接改为中文编码方式。这种方式

Only ensures that the insertion can be executed normally, but when inserting the subsequent data? ? ? Garbled characters. To be further resolved.

Continuing with the above question, I checked the PHP source file in the Apache directory and found that the encoding method of the page was ANSI, so I changed it to utf8 format. Then add the following code before executing the SQL statement command:

mysql_query("set names utf8");

This sentence means: Make the encoding of php written to mysql as utf-8

This can prevent mysql from being viewed in phpmyadmin Chinese data is garbled! //Very important! ! Then perform the insert operation again, and the Chinese can be inserted into the database normally, no longer? ? ? The format is garbled.
