Sloppy $_SESSIONS ?

[Joseph_Sliker]

Hi;

As I don't regard myself as being a "real" programmer, I am just looking for kind of general comments on the use of $_SESSIONS.

Once I figured out how to use $SESSIONS (in a very basic way) I believe I may have gone a little bit nuts with them. The stuff I write for my work-related websites pull all kinds of stuff out of MYSQL database tables and stick this stuff in $SESSIONS to save queries from running every time a page loads/reloads. There may be dozens of $_SESSION sub_keys/multidimensional arrays with (sometimes) megs of data contained therein.

If the users do a proper logout from any of my pages (that require logins) I believe in most cases...at least on the newer pages...the $_SESSION is killed. But if they just close their browsers or head elsewhere, am I taxing server resources for no good reason?

If the user is not actually loading a page and running a PHP script that uses $_SESSION, then you aren't really doing anything except using up a bit of disk space.

...and disk space is cheap.

And tech support contracts aren't. I'm currently wishing to High Heaven itself that someone who wrote a "professional" package would have given thought to what happens when you scale one of their 120+ tables past 10K entries or so, and then prepare every possible query they think they'll need in PDO. :glare:
