The first day of contact with php, read the w3 tutorial. The problem is weak and has very few points.
Mysql may have multiple databases (database 01, database 02, and database 03)
Should I write conn. php as follows?
$ Conn = mysql_connect ("mysql database address", "username", "password ")
Mysql_select_db ("database 01", $ conn );
?>
And then in all files
