Is there way user to call function when exiting browser?
More special -> i want all to clear all DB Caches when user close website or exit browser.
And is there way to cache just one or few query ?
$this->db->cache_on();
-- query --
$this->db->cache_off();
?

I don't believe this is possible with JavaScript.

It is possible but not sure if it is reliable across all browsers:

Basically use that to then call an ajax method to do your cleaning.

That method does not distinguish between closing the page and refreshing it. Just something to consider.

Maybe add a Destructor to your class.
See PHP Net

I agree with InsideFX - add a destructor to your class.
As a side note, there are ways using Javascript to process data when leaving the page (either going to new page, refreshing, or closing browser). I coded this for a data sensitive project where we had to be certain the user was aware they were leaving/closing the page.
