By default session data is stored in files in /tmp. This can be
changed in php.ini. You can also completely override the session
management system allowing you to store the data anywhere you want.
For example: http://stut.net/blog/2008/07/20/mysql-sessions/
You can indeed access and manipulate the session array just like any
other array but there's one important different. Session array keys
must be valid variable names. This means that you cannot use numeric
indexes, and there are a few other restrictions. For more info see the
manual (http://php.net/language.variables).
