if (!$success)
die ("<b>Cannot connect to database, check if username, password and host are correct.</b>");
$success = mysql_select_db ($database);

回答1:
MySQL extension was deprecated in PHP 5.5.0, and it was removed in PHP 7.0.0. Instead, the MySQLi or PDO_MySQL extension should be used.
Use MySQLi-connect insted of MySQL_connect
as well as instead of mysql_select_db use mysqli_select_db
EDIT 01
in mysqli_connect you can select database too
$link = mysqli_connect("127.0.0.1", "my_user", "my_password", "my_db");

You have to stop using mysql_* functions. These extensions have been removed in PHP 7. Learn about prepared statements for PDO and MySQLi and consider using PDO, it's really pretty easy.
