4. Mysql and Mysqli
The Mysql_* and Mysqli_* family of functions were both
created to give a programmer methods of interacting with a
MySQL database using PHP.
For instance, when we want to connect to MySQL and open
communication to it, we use mysqli_connect. Then to close
that same connection we use musqli_close Not very
complicated.
After added Mysqli family of functions with PHP5, it has
improved efficiency, speed, code, security and interfacing due
to the way the new model is structured.
