Go to http://localhost/my.php 6. test your code.
  20. 20. MySQL-PHP ConclusionMySQL-PHP Conclusion MySQL & PHP, presented by David Sands 21 ➔ MySQL is open-source and PHP is open-library. ➔ MySQL and PHP work well together. ➔ Free. Fairly simple and familiar to program with. ➔ MySQL is fast enough, but PHP is fairly slow. ➔ Many real-world applications on-line or even in a local network. ➔ If you are sick of MySQL command line, go get a web server with PhpMyAdmin.
