We then used the `getAll()` function to retrieve an associative array of all the rows and stored it in a variable called `$rows`. Finally, we looped through the rows and outputted the username and email of each user. The package library used in this example is the MySQLi extension for PHP, which allows for accessing the MySQL database.
