Also just to throw this out, you can also use the session_set_save_handler function. This will let you store your sessions wherever you see fit. file system, database, etc. Comes in handy when you're on multiple web servers. http://us2.php.net/session_set_save_handler

Living to learn every single day. Although I find this feature very useful (storing session data in a database for e.g. mysql) I didn't find any good example in the manual or anywhere near using it. Can anyone enlighten me on this ?

Stut, I have a question about your Read() method. You are initializing a variable called $retval, but then doing nothing with it. Then you are returning the result handler whether is it a db handle or a result set. Also, you are running mysql_free_result on that result variable before returning it.

Indeed, that was pretty messed up. That's what happens when you edit code in WordPress. Thanks for the heads up, I've updated the post.

Plus, what does the ampersand before the method name do for you?

It tells the function to return a reference. Session data can be pretty big so on older versions of PHP this can save a fair amount of memory. With CoW now in place in later versions it has no effect at all but I've left it it for compatibility. -Stut -- http://stut.net/
