I believe Adrian was showing how ADODB uses a Unix command to clean  
up it's files and saying that you could also use a Unix command.  I'm  
not sure I would call it "3rd party" if you're always using a unix- 
based server.  Of course, it wouldn't be portable to Windows.

At any rate, you can use PHP's filesystem functions to go through  
your directories and figure out the last time they were changed via  
filemtime(): http://us.php.net/manual/en/function.filemtime.php

On a side note, if you use custom session save_handlers like I  
mentioned before, then you can know which sessions are active.  I use  
custom save_handlers to store all of my sessions in a database rather  
than in temp files.  Then I can just query the database to find  
active sessions.  The only downside is I'm not sure what libraries/ 
classes there are for storing sessions in a database that are easy to  
use and up to date.  As I'm sure Chris' recent presentation showed  
(unfortunately I had to miss it... audio recording?), there are many  
ways for sessions to be compromised.

Anyone know of a good, up-to-date, database session library?  I  
originally used DB_eSession, but it hasn't been updated since 2004  
and my version has been very customized and patched over the years.   
I think I'm happy with it, but would like to review some other code  
if there are other options out there.

Thanks,
Rob
