No, not in this case, TNP, at least it won't be anything rigorous.
Session handling can be changed for an existing application without
breaking it.
You have to do the following:
1) Change for this application the session storage
session_set_save_handler will take care of that.
The easiest way to do this is by adding a file of yourself somewhere
where you define the settings and call session_set_save_handler.
Maybe the existing application has a file that is included everywhere
(which is very common), then simply add you file to it (via another
include, use full path to your session-definition-file to avoid
complexities with include from other directories)
2) Write the appropriate functions you name in the above function
3) Of course, add a table to the database for storage.
There are a few examples on the net to be found to do this.
If memory serves me well, adodb abstraction layer has one ready-to-go
build in.
From the application point-of-view, there will be no change.
Good luck,
Erwin Moller
