Explanation of Values:
----------------------
-- **hostname** - The hostname of your database server. Often this is
- "localhost".
-- **username** - The username used to connect to the database.
-- **password** - The password used to connect to the database.
-- **database** - The name of the database you want to connect to.
-- **dbdriver** - The database type. ie: mysql, postgres, odbc, etc.
- Must be specified in lower case.
-- **dbprefix** - An optional table prefix which will added to the table
- name when running :doc:`Active Record <active_record>` queries. This
- permits multiple CodeIgniter installations to share one database.
-- **pconnect** - TRUE/FALSE (boolean) - Whether to use a persistent
- connection.
-- **db_debug** - TRUE/FALSE (boolean) - Whether database errors should
- be displayed.
-- **cache_on** - TRUE/FALSE (boolean) - Whether database query caching
- is enabled, see also :doc:`Database Caching Class <caching>`.
-- **cachedir** - The absolute server path to your database query cache
- directory.
-- **char_set** - The character set used in communicating with the
- database.
-- **dbcollat** - The character collation used in communicating with the
- database.

-.. note:: For MySQL and MySQLi databases, this setting is only used
- as a backup if your server is running PHP < 5.2.3 or MySQL < 5.0.7
- (and in table creation queries made with DB Forge). There is an
- incompatibility in PHP with mysql_real_escape_string() which can
- make your site vulnerable to SQL injection if you are using a
- multi-byte character set and are running versions lower than these.
- Sites using Latin-1 or UTF-8 database character set and collation are
- unaffected.
-
-- **swap_pre** - A default table prefix that should be swapped with
- dbprefix. This is useful for distributed applications where you might
- run manually written queries, and need the prefix to still be
- customizable by the end user.
-- **autoinit** - Whether or not to automatically connect to the
- database when the library loads. If set to false, the connection will
- take place prior to executing the first query.
-- **stricton** - TRUE/FALSE (boolean) - Whether to force "Strict Mode"
- connections, good for ensuring strict SQL while developing an
- application.
-- **port** - The database port number. To use this value you have to
- add a line to the database config
- array.::
