Hey, nice article. I’ve tried doing something similar in a project of mine using something called mSess from:

http://www.virtualthinking.com/loadhtml.php?where=scripts&what=art_show.php&db_target=00000000024

It doesn’t implement a custom session handler, but it works in a similar manner, and has the added benefit of being able to work with traditional PHP sessions at the same time. Fairly easy to use if you use the sample files as a reference.

It’s a CC based license so it’s flexible to incorporate.

Only consistent way how to count users online, if sessions are stored in memcached is
to have your own session handler and implement full database backup, so new sessions are also created in db as references and cleaned standard way if memcache session is destroyed in runtime or by garbage collector. Under these conditions you can use standard queries to retrieve number of users online and other usefull stats that are problematic to get from MC.
You can also create file based backup with simple counter (tried it myself and works), depends what level of flexibility and possible statistics you want to have.

Another approach is to create backend collector that fetches content of MC server and stores results in MC object. This is however against MC nature, so i would stick with DB or file backup.

Yes, memcached is great, but it is a cache nonetheless that is stored in memory. In case you run out of memory for the memcached daemon, your session data might end up getting garbage collected. I personally recommend using an memcached session handler backed by a mysql database.

For security purpose i also to save sessions in database rather than using flat files. Thou you would delete the file when you delete your sessions, but the file will remains readable by any script or human.
