The dbClass for PHP isn't an eyecatcher, but it´s working solid and save. It can be used for simple mysql queries and manipulation.
To get started you only need to change the database settings inside config.php
Initialize the class
$db = new db(); //create instance
$addValues['title'] = 'someTitle';
$addValues['someNumber'] = 42;
$insert_id = $db->insert('tablename', $addValues);
UPDATE ROW IN TABLE
$updateValues['title'] = 'newTitle';
$db->update('tableName', $updateValues, array('id', $insert_id));
SELECT FROM TABLE
$allRows = $db->select('tableName');
SELECT FROM TABLE WHERE ...
$specificRow = $db->select('tableName', array('id', $insert_id));
DELETE FROM TABLE
$db->delete('tableName', array('id', $insert_id));
