[geeklog-devel] CAPTCHA v3.0 removes reliance on PHP sessions

[Joe Mucchiello]

I would say it should support nothing but read and write. Though I 
suppose an API could be created. What happens if the value of an 
array member is itself an array? Or if the array have a resource or 
object in it? No, leave it up to the code that wants to save the data 
to know how to save and load it. It is faster for you to code calling 
DB_save in a loop to save the array and to call DB_query with a LIKE 
clause to read the data than it is to write a robust save/load that 
can handle any data structure. Though if I get bored I'll give it a shot.

At a minimum I would probably provide a few helper functions:

function SESS_getSessionVar($name, $default = NULL); // if not in db 
return default do not modify db
function SESS_getAndSetSessionVar($name, $default = NULL); // if not 
in db set value to default and save to db else return db value
function SESS_setSessionVar($name, $value);
function SESS_issetSessionVar($name); // return true if name is in the db
function SESS_unsetSessionVar($name); // delete name from the db
function SESS_clearSessionVars(); // delete all vars associated with 
current session
