A PHP Data object or PDO is an extension that allows us to have a consistent way of interfacing with databases making our communication much easier from within our project. The first step in working with our data is to use a database specific PDO Driver.
If you are unable to trigger an Exception by just misspelling the database name, try changing it to look in a different location.
Such as:
$db = new PDO('sqlite:/database.db');
Notice the / instead of the ./ which is a very common error.
