Why are the exported data in Chinese garbled characters and the following code is used to back up the database? why are the exported data in Chinese garbled characters ??
// Back up the database
Define ('in _ fdyu', true );
Require ('Des/config. php ');
// The account, password, and name are all uploaded from the page.
If (! Mysql_connect ($ db_host, $ db_user, $ db_pass) // connect to the mysql database
{
Echo 'database connection failed. check the database and try again ';
Exit;
}
If (! Mysql_select_db ($ db_name) // check whether the database exists
{
Echo 'database does not exist: '. $ db_name.'. check the database and try again ';
Exit;
}

Reply to discussion (solution)
$ Mysql. = "insert into '$ table' ($ keys) values ($ vals); \ r \ n ";
It should be in windows.
When the content of a text file is UTF-8 encoded and does not have a BOM header, it is normal to use the editor to open the file with garbled characters.
What should I do?
Wrong. it is normal to import the exported files to the database, but when I import the exported files to the database, the Chinese characters in the data are garbled.
The character set must be declared when imported.
Set names utf8
Set names utf8
$ Mysql = "set charset utf8; \ r \ n"; change this to $ mysql = "set names utf8; \ r \ n"; that's all. thank you!
