$link =mysql_connect ($host, $user, $pass) or Die (Mysql_error ());

So see no problem, you follow #14 posted code to see, and your require ' 20-1.php '; What is it?

1. Test MySQL connection with cmd
2. Write a PHP test for yourself, and a few lines of connection code

has been resolved, that is my space error.
