E.2. Creating a Connect Instance

With all of PEAR, the MDB2 package, and the MySQL driver installed, you can start to take advantage of these new additions. But to do so, you need to understand what MDB2 is providing you with: a layer of abstraction.

In other words, MDB2 knows everything about accessing any major brand of database program you may have installed. You simply use a common set of commands and tell MDB2 which database to access. This means you can migrate to another SQL database such as PostgreSQL and will only have to install the new MDB2 driver and change a single line of code in your PHP file to be up and running again.
