For many
programming languages, it's pretty easy to figure out which
Connector to use. Java has Connector/J, if you're using C# or ASP
you'll opt for Connector/.NET: the clue is in the name.
For PHP however, things aren't quite so straightforward. If you
want to write a PHP application that communicates with a MySQL
database, you have a choice of PHP extensions that you can use:
mysql, mysqli, and PDO_MySQL.
We can simplify that list right away by discounting the
mysql extension...
