**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.
+**compress** Whether or not to use client compression for MySQL or MySQLi.
**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.
