If you are engaged in website development and use PHP-based programming languages, you certainly find extensions that can be used in MySQL. The two extensions are MySQL Extension and MySQLI Extension. Both extensions have something in common, which is equally useful for connecting MySQL to the programming language you are currently using.
Because they have similarities, we recommend MySQLi, do not use MySQL extension. Why, because with MySQLi it is very supportive for MySQL Server features, especially versions that are 4.1 and so on.
